[osg-users] Missing: ShadowTexture:setResolution(width, height)
Should that perhaps be present in the ShadowTexture class? The default 512,512 might not be quite enough all the time. /Anders -- Anders Backman Email:[EMAIL PROTECTED] HPC2N/VRlab Phone:+46 (0)90-786 9936 Umea university Cellular: +46 (0)70-392 64 67 S-901 87 UMEA SWEDEN Fax: +46 90-786 6126 http://www.cs.umu.se/~andersb ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/

Re: Fw: [osg-users] OSG character node kits information
Sorry, didnt see this mail until now. What seems to be the problem? Are you able to build the code? Also, Im guessing here, you will end up with problem using .NET2003 as the project files are now in version 2005! Which means that if you use the old ones, well, there could be some changes that make build hard. This is really unfortunately, and I guess the only way to solve it is to start using CMake as the rest of OpenSceneGraph. This is quite some task though, so I wouldnt mind at all if you would like to have a look at it :-) If not, please email me about your problems and I will try to solve them. I have done just a few minor changes to the code the last few days, mostly regarding class hierarchy due to that I wanted to be able to generate BiTangents for normalmapping of characters. It wont affect the rest of the toolkit, but it made it possible to normalmap a ReplicantBody. Also I was suprised to know that the forward movement of characters also works for eight legged freaks: http://www.vrlab.umu.se/research/colosseum3d/screenshots.html Although, its pretty obvious that spiders more or less follow the terrain, which really requires an update of the follow functionality so it takes into account the normal of the intersected underlying terrain Perhaps for these spiders, they are so big they just walk over things /anders On 5/4/07, Alan R Mecham [EMAIL PROTECTED] wrote: Okay I might be a complete idiot, but I'm trying use ReplicantBody and install it.

Never take anything for granted regarding windows, I guess thats the lesson I learned.

I have a really tricky question regarding distribution of .exe/.dll files under windows XP. I recently updated my VisualStudio with the latest patch (I'm running VS 2005) on my stationary computer. After this, Im not able to take the osg-distribution on that computer and copy it over to any other machine running windows. This also goes for any .exe file that requires dynamic loading. The error message I get on the target computer is: the system cannot find the file: c:\projects\test\test.exe Just that in the console and NOTHING else!! Im puzzled. Im using the same procedure as I have always done for shipping runtimes: - Copying the requires .dll files for osg/producer/ot - Distributing the requires executables (osgviewer for example) - Distributing the vcredist_x86.exe that installs the required runtimes at the target system. Thats about it. Now suddenly after updating VisualStudio with the service pack Microsoft Visual Studio 2005 I get these problems.

[osg-users] CEGUI shows up when rendering text
Hi all (again). Now to another issue. I have an implementation of a CEGUI integration into OSG. It has been working just fine, up until where I have a multitextured Spider (rendered using ReplicantBody) in the scene. As far as I know and can see, ReplicantBody does not set any states explicitly outside a StateSet. The same Now Im not blaiming the spider for the problem, its just something with it that messes up the CE gui drawing. It disappear from the screen, until there is something rendered using osgText, then it pops back into the display! It seems that something in the state is leaking? from osgText that makes it possible to render the CEgui drawable This is what happens: 1. Render CEGUI only - ok 2. Render spider, cegui disappears, if spider is culled, cegui does not come back! 3. add text to scene -cegui comes back 4 remove text - cegui disappears CEGUI is rendered with the stateset: osg::StateSet* stateset = geode-getOrCreateStateSet(); stateset-setMode(GL_DEPTH_TEST,osg::StateAttribute::OVERRIDE | osg::StateAttribute::OFF); stateset-setRenderingHint(osg::StateSet::TRANSPARENT_BIN); stateset-setRenderBinDetails(100,RenderBin); stateset-setMode(GL_BLEND,osg::StateAttribute::OVERRIDE |osg::StateAttribute::ON); stateset-setTextureMode(0, GL_TEXTURE_2D, osg::StateAttribute::OVERRIDE |osg::StateAttribute::ON); stateset-setMode(GL_LIGHTING,osg::StateAttribute::OVERRIDE |osg::StateAttribute::OFF); And in CEGUI:drawable() Im using the same state settings as in the osgcegui example: renderInfo.getState()-setActiveTextureUnit(0); renderInfo.getState()-disableAllVertexArrays(); m_ui-getSingletonPtr()-renderGUI(); Replicantbody (the spider) is using the state: submesh_state_set-setTextureAttribute(map_id, texture); submesh_state_set-setTextureMode(map_id, GL_TEXTURE_2D, osg::StateAttribute::ON); submesh_state_set-setMode(GL_TEXTURE_COORD_ARRAY, osg::StateAttribute::ON); Im guessing that one of the drawables (ReplicantBody, CEGUI) is leaking/missing a StateSet setting.

[osg-users] osgexp, multiple textures
Hi, slightly OT, but I thought I would ask and see if anyone knows why osgExp plugin for Max doesn't export textures for all channels (Map id:s) I have a diffuse in MapID 1 Normal map in Bump, MapID 2 The only thing that comes out is the diffuse. In the code for osgExp it seems to iterate over all submaterials exporting each and everyone (if they belong to different MapID:s, otherwise there is a clash).

Re: [osg-users] Re: Collision in osg
The bounding sphere of a node is actually generated from a a bounding box surrounding the Drawable (geometry) leaf. This makes the bounding sphere a crude approximation of the real size of your sphere. Therefore I would recommend a parallel structure for doing collision detection. Depending on the number of collisions, and what information you need (boolean query/ penetration, normal) there are quite a few different ways to go around this. If you only need boolean query (intersection yes/no) and you have lots of spheres of similar sizes, then a spatial hash is a good alternative. Its very fast for this thing, you can have 100.000:s of thousands and still get good performance unless you have them occupying the same space. Other efficient datastructures/algorithms are octrees, KD-trees, sphere-trees, Separating Axis test, ... It all depends on what scalability you require from your app. There are quite a few libs that does very efficient collision detection. Osg is mostly for rendering, and ray/scene intersection tests, anything beyond that you have to add yourself... There are quite a few approaches to add ODE for collision detection/dynamics Look at the osgwiki for Don Burns osg/ode example. /Anders On 5/11/07, Rémi Chaignon [EMAIL PROTECTED] wrote: Hi all again, (sorry I pressed the wrong button) In my program, I am creating 2 spheres in the same way: code // Create a sphere centered at the origin, unit radius: osg::Sphere* sphere = new osg::Sphere(osg::Vec3f( 0.f, 0.f, 0.f), 1.f); osg::ShapeDrawable* sphereDrawable = new osg::ShapeDrawable(sphere); sphereDrawable-setColor(osg::Vec4f(0.4f, 0.2f, 0.8f, 1.f)); osg::Geode* sphereGeode = new osg::Geode(); sphereGeode-addDrawable(sphereDrawable); osg::MatrixTransform* sphereTransform = new osg::MatrixTransform(); sphereTransform-addChild(sphereGeode); return sphereTransform; /code Then I want to know if the spheres collide, to do this, I've tried different ways: - Get the bounding sphere of the node (getBound()) Result: A collision is detected even when the spheres are far from each other. - Get the bounding sphere of the geode (getBound()) - Get the bounding box of the geode (getBoundingBox()) - Get the bounding box of the drawable (getBound()) Result: A collision is always detected.

Re: [osg-users] textual description of 3dsmax models
We have a slightly modified osgExp (based on a older osgExp) that does
just that.
We use the user properties for description of physical objects.
Unfortunately it contain some more things that are very specific to
our framework, as we parse the textual information using ConfigScript
(also available in ReplicantBody) so that we can write things such as:
Object {
PhysicalProperties {
Mass 1
Material 2
}
}
etc...
So during export it will catch syntax errors.
I have rar:ed our version here:
http://www.vrlab.umu.se/research/colosseum3d/material/osgexp.rar
You could probably rather easy extract the code that take the user
properties and convert it to Node description.

in 3dsmax and, hopefully, it should be exported as well as the model...for

[osg-users] OpenThread library name
Windows XP, VisualStudio 8. I just checked out svn osg and OT and got some problems during build. I'm using a separate checked out version of OT, so I'm using the OPENTHREADS_DIR env variable to specify the path to OT. 1. It seems that OT generates OpenThreads(d).lib (and not OpenThreadswin32(d).lib as before) 2. OpenSceneGraph still refers to the name OpenThreadswin32.lib 3. In windows there is no really good path where to install headers and libs. Is the new convention to install it to c:\program files\OpenTHreads something that the community has decided or is it a proposal to a new standard;-) ? It now also seems that one HAS to install OpenThreads to get the correct include/lib path for cmake. Otherwise the library resides under debug or minsizrel or release. This makes it slightly harder to use multiple versions of the library, as one has to install all of them to some common path. So what is the opinion of other windows users about path names? /Anders -- Anders Backman Email:[EMAIL PROTECTED] HPC2N/VRlab Phone:+46 (0)90-786 9936 Umea university Cellular: +46 (0)70-392 64 67 S-901 87 UMEA SWEDEN Fax: +46 90-786 6126 http://www.cs.umu.se/~andersb ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
Re: [osg-users] OpenThread library name
What if you want to replace OpenThreads temporarily for a patched one? What if you decide that you want to build with or without debug symbols in the release library? Copying libs in windows is not a good way to handle these things. Together with .lib/.dll there are pdb etc for debugging, copying them back and forth is not very effective. I rather prefer the unix style suggested by Thibault, we are using something similar, where we make use of the LIB and INCLUDE environment variable that exists for visualstudio. By running a bat-file we set the LIB, INCLUDE and PATH variables to whatever release/library/combination we want, then we start visualstudio with devenv /useenv. My rule is, NEVER store explicit paths in the .vcproj file, it always fails when using multiple versions of libraries. I realize this is not the way Cmake wants it, it rather want to get all the paths, create hard-coded project files with all paths in it, and then keep it like that. Although there is nothing that prevents the user from starting visualstudio with devenv /useenv anyway to make use of LIB/INCLUDE env. variables, so I dont see any problems in that. The only problem right now is that you have to INSTALL before using OT, OSG and osgProducer. What would happen if you specify OpenSceneGraph as install path for binaries/libs? Would it also try to copy header files? Copying header files is even more stupid, as the dates are changed and sometimes you get a major recompile due to that. But if the default installation lib (at least for windows) would be the source directory then I think it would work just fine (as before), and if someone (hope not) want to install code into Program Files or Windows directory then its up to them. /anders On 4/24/07, Wojciech Lewandowski [EMAIL PROTECTED] wrote: I had similar problem but noticed that one may set the same path as Source code, Binary root and Install path. In this case install just moves release and debug libs to lib subdirectory of the project and dlls and executables into bin subdirectory of the project. It does not copy Include dirs because they would land in the same dir. For example: I keep my all my OSG related projects in C:\dev\OSG_SVN directory. So I use C:\dev\OSG_SVN\OpenSceneGraph directory for all three directory locations for source code directory ( Where is the source code in Windows Cmake ) for binary directory (Where to build the binaries in Windows Cmake) and for install directory( CMAKE_INSTALL_PREFIX variable in Windows Cmake) this produces similar results as defaul locations in older OSG distributions with this exception of Win32 subdir removed from lib and bin.

What if you decide that you want to build with or without debug symbols in the release library? Copying libs in windows is not a good way to handle these things. Together with .lib/.dll there are pdb etc for debugging, copying them back and forth is not very effective. I rather prefer the unix style suggested by Thibault, we are using something similar, where we make use of the LIB and INCLUDE environment variable that exists for visualstudio. By running a bat-file we set the LIB, INCLUDE and PATH variables to whatever release/library/combination we want, then we start visualstudio with devenv /useenv. My rule is, NEVER store explicit paths in the .vcproj file, it always fails when using multiple versions of libraries. I realize this is not the way Cmake wants it, it rather want to get all the paths, create hard-coded project files with all paths in it, and then keep it like that. Although there is nothing that prevents the user from starting visualstudio with devenv /useenv anyway to make use of LIB/INCLUDE env. variables, so I dont see any problems in that. The only problem right now is that you have to INSTALL before using OT, OSG and osgProducer. What would happen if you specify OpenSceneGraph as install path for binaries/libs? Would it also try to copy header files? Copying header files is even more stupid, as the dates are changed and sometimes you get a major recompile due to that. But if the default installation lib (at least for windows) would be the source directory then I think it would work just fine (as before), and if someone (hope not) want to install code into Program Files or Windows directory then its up to them. /anders On 4/24/07, Wojciech Lewandowski [EMAIL PROTECTED] wrote: I had similar problem but noticed that one may set the same path as Source code, Binary root and Install path.

To get an efficient pipeline one would like to avoid 19 different file formats just to get a character to move around. There are already exporters for collada, so its more of a matter of writing a CA library that makes use of it.

Re: [osg-users] Graphical gadgets
Biggest issue was how to get all the resources for CEGUI, but I used a
custom ResourceProvider that helped out.
Sure I can submit the code, but we use CEGUI strictly from lua through
a plugin system, so some things in the code is probably a little bit
too specific for that.
Another issue was how to load several layouts, CEGUI doest really have
a scenegraph, so the naming convention is important...
I have attached the files related to the CEGui rendering/event handling stuff.
We still use producer so one class is actually using RenderSurface to
determine size of renderable surface.
Example of use (not tested/compiled code):
Producer::RenderSurface *rs = viewer-getCamera(0)-getRenderSurface();
m_c3dCEGUI = new C3DCEGUI::c3dCEGUI(rs);
m_c3dCEGUI-init(lua); // we use it together with our lua scripting system
// Add the CEGUI root-node
root-addChild(m_c3dCEGUI-getOsgNode());
Should do it.
To enable it:
m_c3dCEGUI-setToggleKey(osgGA::GUIEventAdapter::KEY_F1); // is also default
When running, pressing CTRL+F1 will enable CEGUI.

Adding vertexbuffer support to ReplicantBody shouldnt be that much work. Wouldnt that make more sense so that the whole osg community would make use of a better character animation toolkit? Although, I dont think it will affect performance that much, the same amount of data have to be submitted, its fewer OpenGL calls, but my experience of glBegin() glEnd() is that its the glEnd() that consumes time, not glVertex() glNormal() calls, as I guess the data is transmitted after the glEnd(). The only really good way to go to get better performance is to do hw skinning... /Anders On 4/18/07, David Guthrie [EMAIL PROTECTED] wrote: The problem with rbody is that it's pushing all of the vertices to the GPU every frame. Using a display list stops the animation because it's precompiling the vertices onto the GPU, so it doesn't change. Using display lists would only help for a stationary character. You can write the vertices straight to a vertex buffer and see some performance benefit, but I don't think rbody supports that. We are currently removing rbody from our engine (Delta3D) to use cal3d straight. Partly so that we can control the rendering. If you want to see more characters and you use a vertex buffer, you can do things like only updating the animations on timer somewhat less than the frame-rate, which will allow a vertex buffer to not be written to the card every frame. Another option is to do hardware skinning where you only use cal3d to update the bone positions and have a vertex shader use the bone positions to move the vertices of static pieces of geometry in the GPU.

Re: [osg-users] Audio Integration using osgAL
Sorry, small keyboard, large fingers ;-) Hit send before I was done... There is also a couple of depricated classes NetStream.cpp and NetStreamUpdater.cpp that uses CommonC++ for recieving a stream of sound over a UDP channel. That code is VERY old and will not compile with the current version of osgAL. I removed them mainly to reduce the dependencies for osgAL (thus removing CommonC++) Shouldnt be hard to implement that using the same stuff as the osgCluster example. /Anders On 4/4/07, Anders Backman [EMAIL PROTECTED] wrote: Do you mean buffering of a sample onto a source?

Re: [osg-users] Audio Integration
osgAL is based on OpenAL. OpenAL under windows will support anything that your current hardware is capable of, if you have the latest and matching hardware drivers. For example using a Creative xFi will also give you true HRTF out of the box using osgAL. Just set the speaker setting in the drivers for the soundcard to HeadPhones and you will get HRTF (there could be another setting you have to do for HRTF, but other than that it should work). The same goes for 5.1, just set it in the driver for your creative sound card (any other card will probably only do simulated 3D sound on the CPU which is not what you want). Under linux the situation is different. There is as far as I know no hw support for 3D sound. Creative have stated that they will release hw drivers supporting EAX4.0 etc under linux, but I havent seen it yet. /Anders On 3/31/07, RJ [EMAIL PROTECTED] wrote: Thanks Robert, I have osgAL installed on my machine and i will try it.

Re: [osg-users] cal3d LODs
For ReplicantBody there is a method (rbody::Body::setLodPoly()) that set the current LOD on the Cal3D mesh. I remember vaguely that I implemented a simple LOD functionality, but it doesnt seem to be in the repository anymore... Now the new cal3D, will that be API compatible with the old one? That is, would it be possible to integrate it into ReplicantBody without substantial changes? /Anders On 3/16/07, Zach Deedler [EMAIL PROTECTED] wrote: Jan, Awesome information. Thanks a lot. From what I believe you are telling me is that, we can create the mesh models as one max file, and export them out just as you would before. Thus, if you look at the model in max you see a bunch of overlapping meshes. If I attach LOD's around these then I'm set. What I'll do is have the modeler create the meshes named a certain way, so that I can traverse the scene graph and add the LODs. This is how I was able to switch on and off objects in a models hands. I search for named nodes, and attach switch nodes. If I end up with anything I can give back to the osg community, I'll be sure to post it. I'm thinking we need a document of how to create the LOD cal3d model, and an InsertLODVisitor. Possibly this could be added to the exporters, along with the non-working dynamic LODing. Thanks.

Each vertex has a weight on it to determine this. Thus, wouldn't applying an LOD to it cause a problem in the middle of an animation? Sure, but you do not do this in the middle of doing the calculation. You move the skeleton to one pose, then deform the skin and render it. If during the next frame you are deforming another version of the skin (another LOD level), it doesn't have an effect since the skinning is recalculated every time. Are you saying I should be able to export two cal3d meshes and then hardwire the LOD's in? For example, for a model with a torso, and head; I'd export a low-level LOD and high level LOD for both the torso and head. Then, I could use some traversing code to stitch the model back into one model? I'm just afraid the animation won't allow for the different meshes, but maybe I under-estimated the code. You can have several meshes attached to a skeleton in Cal3D, if I remember correctly. So switching them shouldn't be an issue. Another solution which I have used was to just load the whole model (not only mesh) several times and switch among them using the LOD node in OSG. Crude, but works. It worked nicely also with the Impostor node - e.g. I had 3 LOD levels and the 4th one was an Impostor - the guy was replaced by an autogenerated billboard when too far away, saving on animation and rendering time. I had over 10 000 Cal3D skeletons rendered like this. Does Blender allow you to export an LOD'd Cal3D model? The exporter tries to calculate the LOD levels for Cal3D (the mesh collapsing system), however it doesn't really work, as far as I remember. Perhaps it was fixed in the meantime, but I doubt it. The idea was to export one model with the full amount of faces and then the exporter would generate the required information for Cal3D on how to collapse the edges based on the information about which piece of mesh is using which material (i.e. hand collapses only on hand and not into body so that the hand is not lost). Unfortunately the code didn't work, in fact it never finished the calculation loop for me :( Regards, Jan -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Mandriva - http://enigmail.mozdev.org iD4DBQFF+d7Xn11XseNj94gRAo85AJYvTg0Zm1OsRDejYm9dP09docFCAJ4mNydw SMXQmlUcVc+Apr1NIEx5xg== =p14b -END PGP SIGNATURE- ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/ ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/ -- Anders Backman Email:[EMAIL PROTECTED] HPC2N/VRlab Phone:+46 (0)90-786 9936 Umea university Cellular: +46 (0)70-392 64 67 S-901 87 UMEA SWEDEN Fax: +46 90-786 6126 http://www.cs.umu.se/~andersb ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/

With QUAD_STEREO (supported on Nvidia Quadro cards and other professional ones) you can direct your stereo to be a interlaced stereo signal (color interleaved, vertical interlace, on-board DIN port), and a few more modes.

[osg-users] Leak in StateSet
Hi. I have discovered a rather serious problem regarding a potential leak? in StateAttribute. Im using a rather new svn version of OpenSceneGraph (checked out 17 february). The files illustrating the problem is available at: http://www.hpc2n.umu.se/staff/andersb/osg/state_problem/ j.jpg a.jpg state_problem.osg The problems I can see is: 1. The texture r.jpg is applied to parents of textured geometry with OVERRIDE on. Still nodes below this parent is using v.jpg which is what is visible. So no r.jpg to be seen in the scene. A (texture unit 0 = r.jpg with osg::StateAttribute::OVERRIDE|osg::StateAttribute::ON) | | G (texture unit 0 = v.jpg With only osg::StateAttribute::ON) 2. Look what happens when the thin box at the bottom is culled, then suddenly the middle box is rendered non-textured. /Anders -- Anders Backman Email:[EMAIL PROTECTED] HPC2N/VRlab Phone:+46 (0)90-786 9936 Umea university Cellular: +46 (0)70-392 64 67 S-901 87 UMEA SWEDEN Fax: +46 90-786 6126 http://www.cs.umu.se/~andersb ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
[osg-users] Problems using QueryPerformanceCounter()??
Is there anyone out there experiencing strange hang and timing problems on
dual CPU/Core/HT windows XP machines?
except for the ordinary laptop-timing problems of course ;-)
Im currently debugging something that gives me gray hair, and someone
suggested that it could be a potential problem coming from the fact that
QueryPerformanceCounter() is used (osg::Timer)
I have an app that runs just fine for a while (can be 1 minute, sometimes
30) and then it hangs, and it never occurs in debug-mode (of course!) so its
quite tricky find the cause for it.
I have already found one reason for the hangs, and that was in Producer
where a OpenGL timer query never returnedBut that is fixed (by skipping
after 1000 iterations).
It seems to be quite a few developers with this problem when I searched the
web.
For example:
http://www.virtualdub.org/blog/pivot/entry.php?id=106
It seems that when a thread is moved in and out between different execution
cores/CPU:s it can drop timing or even get negative timing results
It also talks about hangs (which I guess could be a second order problem
that comes from the timing problem).
Right now Im looking at something that looks like a hang inside
osg::Timer::tick()
So is there anyone else experiencing this?
There is a bunch of recommendations from MS:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/directx9_c/Game_Timing_and_Multicore_Processors.asp
- using QueryPerformanceCounter from only one thread
- setting SetThreadAffinityMask so that the timing thread runs on only one
CPU/Core
- clamping the subtraction result so you never get a negative one:
inline double delta_s( Timer_t t1, Timer_t t2 ) const { return
(double)(t2 - t1)*_secsPerTick; }
Should be:
inline double delta_s( Timer_t t1, Timer_t t2 ) const { return
(double)osg::clampAbove((t2 - t1), 0)*_secsPerTick; }

Is there a specific reason for not using epsilon tests for a float? I can
think of quite a few situations when this would fail.
I guess, there is only one situation when this would succeed for sure, and
that is after a call to makeIdentity().
This also goes for quite some of the Vec3, Vec4, Quat code too.
All comparisons such as:
inline bool operator == (const Vec3f v) const { return _v[0]==v._v[0]
_v[1]==v._v[1] _v[2]==v._v[2]; }
Would effectively fail in most situations, as comparing floats directly is
something that is not recomended.
Instead something like the following should be used:
#define EPSILON 1E-16
#define EQUAL(A,B) (abs((A)-(B)) EPSILON)
inline bool operator == (const Vec3f v) const { return EQUAL(_v[0]-v._v[0])
EQUAL(_v[1]-v._v[1]) EQUAL(_v[2]-v._v[2]); }'
Comments?

Re: [osg-users] float == 1.0f?
Sure, I agree, the EPSILON was there for an example, so where the rest of
the macros.
I dont want to introduce a macro with a hard limit into a library, Im just
pointing out that when is an exact float test really appropriate?
An example:
osg::Matrix m1, m2;
m1.makeRotate(osg::PI_2, osg::Vec3(1,0,0), osg::PI_2, osg::Vec3(0,0,1),
osg::PI_2, osg::Vec3(0,1,0));
m2 = m1;
m1.invert(m1);
std::cerr m1*m2 std::endl;
std::cerr Matrix I: (I.isIdentity() ? 1 : 0) std::endl;
{
1 -4.44089e-016 4.71028e-016 0
-4.44089e-016 1 -4.71028e-016 0
-4.71028e-016 4.71028e-016 1 0
0 0 0 1
}
Matrix I: 0
Now, for most cases I would call I an Identity matrix, and I think even Dr.
Goldbergs would agree?
But for the reasons of limited resolution, it is not, when considering the
equality test.
For example, if I for some reason I would calculate a color for two
materials, and color1 ends up being within 1e-16 close to color2 and
So this would be the effect: color1-color2 = vec4(1e-12,1e-12,1e-12,1e-12);
If I then use color1 and color2 in two separate Materials, lets say for
Diffuse color.
During a test of equality (StateSorting), these two colors are considered
different and are therefore not merged. But for most applications they ARE
equal, which in this case would mean
that the State sorter failed to recognize that.
Couldn't that cause a problem?
My point is, for most scientific applications (read simulators dynamic
systems)
float a,b;
if (a==b)
is considered to be somewhat banned.
Im not saying its wrong, it all depends on what you want to test. But from
browsing the net on the topic, and from personal experience the use of
exact equality tests for floats is not recommended.

Well, that is wrong too.
In effect you are making fixed point arithmethic from floating point
arithmethic.
Somehow more correct would be:
#define EQUAL(A,B) (abs((A)-(B)) =
std::numeric_limitsdouble::epsilon()*max(abs(a), abs(b)))
But even that is not the real trueth...
See Goldbergs excelent paper 'what every sceintist should know about
floating
point arithmetics' (just google for that).
Doing that right is highly dependent on the application you need.
Due to error accumulation your proposed bound is too hard, since this test
only checks for roundoff in the representation, not roundoff that happens
when operating on such numbers.
I cannot speak for osg, but from my point of view the implemented method
is
perfect. If you want to have an 'equal up to floating point precision'
test I
would prefer having a new set of methods that do not test for exact
equality.
From my experience with that kind of stuff, you should not hard code that
EPSILON here - may be provide a sensible default value but no hardcoding
...

I have a class that I wanted to add to OpenThreads. I got ok several months ago, but nothing has happened... So perhaps I can email you the stuff instead Robert so you can review them for inclusion into OpenThreads? I would like to lift that class outside of osgHaptics. Also, the osgDB::reentrentMutex is another class that should go into OpenThreads, right? Its really better suited for OpenThreads than osgDB.

Re: [osg-users] Missing descriptions
Hi again. After a quick debug session through the optimizer (thats one long file 4103 lines and I think every single line is executed during an optimization pass) , anyway, Its hard to say what really goes wrong, but there IS check for that there are descriptions within a node (in the call to isOperationPermissibleForObjectImplementation) but during the FLATTEN_STATIC_TRANSFORMS pass it is not called. I think that this comes from the fact that during this pass the scene is traversed all the way down to a geometry, collecting the static transforms on the way and during a back-traversal of the parents of the Geometry they are actually marked for removal, and there is no call to isOperationPermissibleForObjectImplementation during that back-traversal.

I would expect the optimizer to remove any STATIC transforms etc. after it has actually traversed the scene, not before? Or is the Optimizer incorporated into the loader nowadays? I have just done an osgconv on your file, and the descriptions remain in place when the Optimizer is switch off, but are optimized away along with the static MatrixTransform they are attached too. Obviously the Optimizer isn't checking for presence of descriptions when deciding whether it can optimizer away a node. It does check for a number of parameters such as callbaks, so adding a test for descriptions should be easy.

Re: [osg-users] Performance drops when using 4 or more camera nodes (RTT)
What is the hardware you are running on? Platform? On 22 Jan 2007 23:27:35 -, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Hi, I'm using floating point textures as my targets for multipass RTT. In my tests I have noticed that if three or less camera nodes are set up using GL_RGBA16F_ARB internal format textures, the frame rate stays at a constant 75FPS when only the texture is rendered to the screen (i.e. the texture is rendered over the full window). If I add an additional camera node, the frame rate drops to 15 FPS. Five nodes yields 8FPS, and 5FPS are achieved with six nodes. Also, if I set the texture to render to 1/4 of the screen and position the main camera so that the actual scene being rendered to texture is visible, I'll get 25FPS for the three camera node implementation. I'm setting up my textures with internal formats of GL_RGBA16F_ARB, a source type of GL_FLOAT, and a source format of GL_RGBA. The FBO is set up like: fbo-setAttachment(GL_COLOR_ATTACHMENT0_EXT, osg::FrameBufferAttachment(texture)); fbo-setAttachment(GL_DEPTH_ATTACHMENT_EXT, osg::FrameBufferAttachment(new osg::RenderBuffer(512, 512, GL_DEPTH_COMPONENT24))); My min/max filters are set up as NEAREST. If I change my textures to internal formats of GL_RGBA and the source type as GL_UNSIGNED_BYTE, my performance is great. Any thoughts?

[osg-users] Slightly OT: Version handling VisualStudio
Hi all. Im wondering how people handle the fact that each VS version upgrades the project files making it effectively impossible to support several versions of VisualStudio, unless: -You manually reflect changes back into .dsw (VC6) -Find a tool that converts .sln/.vcproj (in VC8) back to VC6. - Use an external make system (CMake, SCONS) I have been using a tool called prjconverter which could handle the conversion between VC7 and VC6, but it cant handle the new project files. Now is there a good solution, except start using CMake or SCONS or some other external make system? /Anders -- Anders Backman Email:[EMAIL PROTECTED] HPC2N/VRlab Phone:+46 (0)90-786 9936 Umea university Cellular: +46 (0)70-392 64 67 S-901 87 UMEA SWEDEN Fax: +46 90-786 6126 http://www.cs.umu.se/~andersb ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
[osg-users] daeSafeCast in dae/daeUtils should be removed
Hi. I just did a svn update of the Collada_dom and tried to build the Collada (dae) plugin. It seems that there is an ambiguity between a method defined in daeUtils.h (daeSafeCast) and one now also existing in daeElements. The one in the osgPlugins/dae/daeUtils.h should be removed. Then it compiles fine. As daeSafeCast is the only method defined in daeUtils.h I guess the whole file can safely be removed. /Anders -- Anders Backman Email:[EMAIL PROTECTED] HPC2N/VRlab Phone:+46 (0)90-786 9936 Umea university Cellular: +46 (0)70-392 64 67 S-901 87 UMEA SWEDEN Fax: +46 90-786 6126 http://www.cs.umu.se/~andersb ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/

Re: [osg-users] Keyrepeat windows
MM, not a very clean solution, I mentioned that in my previous post.
Its better if we dont get any event at all.
Otherwise, windows will burst out keyboard events through producer in vain.
Also, what if you start the app with a keyboard pressed?
Not very likely, but if you want to catch everything, it could be a problem.
(Users are likely to cause problems, if they can, they will, without
them it would be a lot easier to develop software :-)

[osg-users] SIGRAD Conference 2006
Its time for the annual SIGRAD conference. This years Theme: Computer Games Date: November 22-23, 2006 Location: Högskolan i Skövde, Sweden The SIGRAD conference provides a venue for interaction between academia and professionals within the field of computer graphics in the nordic countries. The special theme for the conference in 2006 is computer games. * The keynote speech for SIGRAD'06 is about rendering technology used in the current generation of game engines. Torbjörn Söderman (Lead Rendering Programmer) will talk about the history of rendering technology in the game industry and Johan Andersson (Rendering Architect) will give an overview of the architecture and rendering systems of DICE's new Frostbite engine that powers the upcoming Battlefield: Bad Company for the Xbox 360 and PlayStation 3. * The papers presented in the Academic session will cover a wide range of topics ranging from computer graphics theory to more practical topics such as the use of graphics for serious gaming applications and the simulation of physics. * During the interactive sessions the University of Skövde will present research on human-computer game interaction and serious gaming, the Royal Institute of Technology will present work on the VERSE project which aims to create a protocol for connecting 3D Application with low latency connections. * Skövde is conveniently located between Gothenburg (1 hour by train) and Stockholm (2 hours by train) so it is possible to visit the conference as part of a normal work day.

Its been replaced by the osg::CameraNode which handles everything that has to do with rendering to textures. So osgprerender.cpp should work as an example for that.

Re: [osg-users] Semi-OT: Plugin architectures
I actually needed something like what you are describing here, a way of linking in external libraries in runtime a while back...What we ended up with was a plugin structure for lua.Its not optimal but it works well. We have a main executable that really doesnt know much about the world, but it has a lua-state and it knows how to load a plugin and register it to lua.
So what we can do is take for example a class:class MyApp MyApp(); void run(); // starts my app and do whatever void doOtherthings() bool shutTheWholeThingDown() ...}write a LuaPlugin class:
LuaMyApp : public LuaPlugin{ virtual void init(); // will be called during loading}Run MyApp class through tolua++ and generate interface binder code, call that from LuaPlugin::init() which registrates the MyApp class into lua.
This results in a .dll/.so luaplugin_myapp.dllSo by starting the main app:DOS main_app myapp.luawith a lua-file that specifies:myapp.lua:--requestPlugin(myapp)
myapp = MyApp:new()
myapp = MyApp:run()So its up to the author of the LuaMainApp plugin if he want to export all of the interface to lua or just the kick-off code.main_app doesnt know anything about MyApp.
There are of course a few Singletons to enable access to a scenegraph and some other things.All this said, I would love to see a slick API/toolset that makes it possible to get COM:ish functionality, while still portable and with a small overhead mainly in use!

Re: [osg-users] Sound...
Sure there is. There is osgAL. OpenSceneGraph Audio Library. Its available from sourceforge. Im actually working on it right now, it use to be two separate libraries, OpenAL++ (a C++ abstraction on top of OpenAL, which is an portable open source 3D sound C api), and osgAL (integration of OpenAL++ into OSG). Im now migrating these two into one, for simpler build/download process. I can only verify the Windows platform right now, but I will start work on testing the linux platform too (we have been using it under both windows and linux for years, but not since the migration). Right now, the new version is only available through svn. SO do a svn checkout from the http://sourceforge.net/projects/osgal, download the ogg-vorbis precompiled libraries and build the osgAL\visualStudio\osgal.sln (in the case of windows). If you are running linux, well, do the same thing and do a ./configure;make but I cant ensure you that it will work without some effort. osgAL/OpenAL++ can load .wav, .aiff soundfiles and attach them to SoundNodes in the scenegraph. You can also use .ogg files, although, thats what Im spending time on right now, to get it to work better than before... There is still some work to do. There are examples in the osgAL/examples directory, both for osgAL as well as OpenAL++.

Re: [osg-users] Sound...
Just realized that this was only part of the truth. OpenAL and freealut is also needed for the build. FreeALUT is a library similar to GLUT, that initializes the OpenAL hardware and load standard wav/aiff fileformats. So the dependency list of osgAL is: - OSG_OT_P (OpenSceneGraph/OpenThreads/Producer) - OpenAL http://www.openal.org/downloads.html - Freealut http://www.openal.org/downloads.html- Oggvorbis http://www.vorbis.com/setup/ There is a very odd thing with the OpenAL binary release from creative under windows though, for some reason they have moved the header-files from AL/al.h to al.h Currently the osgAL code in the repository will assume AL/al.h is used, which probably means that one have to make a AL directory and move the header files over there, I will probably add a #ifdef WIN32 macro for this. The problem is that there are other OpenAL releases available (one from NVIDIA) I'm not sure which path they have taken, probably the standard one... To make things even worse, in the cvs version of OpenAL, they use the AL/al.h version, so someone at Creative took a creative decision somewhere in time ;-) On 10/6/06, Anders Backman [EMAIL PROTECTED] wrote: Sure there is.

I suggest a nice outdoor scene about 10,000 units in diameter. You also need GLSL support. This implementation is fairly complete, but I would like any opinions that you all have (or code to extend it). I don't know if this would make a better example program or nodekit. The big problem I see with making a nodekit is that there are just too many different ways to implement PSSM; I don't know how you could make one nodekit that would satisfy everyone. The angle I took in writing the DirectionalParallelSplitShadowMaps class was to just produce high quality shadow maps, but not to force people to render their scene any particular way. The demo renders your scene in one stage with a shader, but it would be interesting to see what happens if you split the scene into slices and render each slice with a single shadow map. I also did not implement a split scheme like Adrian did. It seemed like everyone uses a different split scheme, and the split scheme might need to be particular to the scene, so I leave that up to the user of the DirectionalParallelSplitShadowMaps class. The class lets you add your scene in pieces: an opaque piece, and a piece with transparency. Then it applies a different shader to each one for rendering the shadow maps. It might be nice to apply a different shader to the opaque and transparent rendering bins, so that the user doesn't need to make this separation themselves. I don't know if this is possible yet, though. On the other hand, no sorting is necessary for rendering objects with alpha into a shadow map because pieces of those objects either become completely opaque or completely transparent in the shadow map. So maybe the rendering big idea isn't the best solution. The biggest thing missing in this demo is good LOD support. I have been trading emails with Robert about implementing good LOD support for shadows, but this effort isn't complete yet. So you might not see shadows cast by LODed nodes. Anyway, let me know what you all think. -- Terry Welsh - mogumbo 'at' gmail.com www.reallyslick.com | www.mogumbo.com Message: 12 Date: Wed, 20 Sep 2006 18:53:04 +0100 From: Robert Osfield [EMAIL PROTECTED] Subject: Re: [osg-users] Parallel-Split Shadow Map with osg [PSSM] To: osg users osg-users@openscenegraph.net Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=iso-8859-1 On 9/20/06, Radu Mihai [EMAIL PROTECTED] wrote: Here's how I think this could be handled: - SSM NodeKit - standard shadow map, using FBO and GL_DEPTH textures there's an point of interest being discussed in the list about doing a depth-only FBO render after the FBO version is running well, there can be some fall-back methods added - derive a PSSM NodeKit based on the previous one I think the approach here would be to have MultiTexturing used in the SSM kit and use that capability in the PSSM kit to do the texture management additionally there will be code to manage the creation of the splits This kind of approach would allow me to combine job-related work with OSG contributions :) If you're interested, and if you think this is a good way to proceed, I'll post the code I have and we can go forward from there. FYI, I should start work on an osgShadow library for the OSG quite soon. The contract is for stencil volume shadows, so this will probably be the intitial back end implementation, however, I'd like to make the interface classes as generic as possible, and support other shadowing algorithms. How easy this might be is very difficult for me to say until one starts lining up various implementation side by side and working out the commonality and the differences, and finding ways to encapsulate the differences neatly.

RE: SV: [osg-users] osgAL setup
I have been using OpenAL for quite some years, it use to be pretty easy. Now, I havent used 1.1, so I started looking into it yesterday. It turns out that they have changed a few things... For example the OpenAL1.1 installer doesnt place include files in /AL subdirectory! The standard ALUT library is gone from OpenAL and is now in frealut, which has to be compiled separately. Other than that, it is not much of a problem I guess. I would like you to elaborate about Frankenstein? Also, it would help to know what kind of runtime errors you get? Does the simple.exe in openalpp/bin work ok? Does the osgal.exe in osgal/bin work ok? SDL wont give you spatial sound, right? It wont give you hw accelerated sound either, right? Does it give you Doppler effects? I havent looked into it for a while... But I dont think so. The only platform independent sw solution that doesnt come with a comercial license is OpenAL. For universitites there are other alternatives. So what I would like to know, is if the Frankenstein resides in OpenAL++ or OsgAL, or if it is an external monster ;-) I have planned to migrate OpenAL++ into osgAL, making build a lot easier when you have the right OpenAL installed. I will try to build OpenAL1.1 and see if I can write a tutorial, or even pack a zip file with the necessary stuff to make it easier to use.

RE: [osg-users] Playing sound in movies (win32)
I guess, if you want interactive spatial sound (3D) osgAL is the
preferred choice as xinelib and quicktime cant do that. That is to have
the sound following the movie node in space.
If you on other hand need codecs to do Dolby Digital etc. then osgAL
(openal) is not the right choice.

Hi Marta,
I'm not yet familiar with osgAL so I'll defer to others on
how best to do it. Also osgAL isn't part of the core OSG so
I can't merge anything that is based on it yet, the wiki is a
good place to post such code though.
The xine-lib and quicktime plugin do there own sound support
without the need for osgAL, does the AVI library you are
using not support this as well?

[osg-users] Initial release of osgHaptics
Hi all. OpenSceneGraph haptic library (osgHaptics) is a first attempt att supporting haptic rendering inside OpenSceneGraph. osgHaptics is available as download and SVN checkout from: http://sourceforge.net/projects/osghaptics Currently it is only built and tested under Windows. It depends only upon OSG-bundle (OSG, Producer, OpenThreads) and OpenHaptics, which are all available under MAC, WIN and Linux. So it should in theory not that hard to port between the different platforms. Currently it uses osgProducer for some reasons (post-/pre render callbacks). There are certainly a lot of room for improvements. So you are all welcome to check it out, try and come back with comments... It comes with to small apps at this time, I will write a few more to document the use of the code in good old OSG spirit!
