[osg-users] manipulator design advice
Hi, I am using the osgManipulator draggers to move objects around my scene. I intend that when the R key is pressed a rotation dragger is used and when the T key is pressed a translation dragger is used. And if any other key is pressed then no draggers are used. The manipulator example applies the draggers from the start and so doesnt face this problem. What is a good way to arrange my scene nodes so that I can switch between drag modes? Originally I thought of using a switch node, but then only 1 transformation at a time would be applied to the model (is that right?) and I want the transformations to be maintained across modes. I could stack the manipulators on top of each other, but then their geometry (created with setupDefaultGeometry()) would overlap. (The API doesnt support disabling a dragger.) My current design is: - put the model behind a transform - when switch mode apply current dragger matrix to the transform and then remove dragger - insert new dragger before the transform This seems very awkward so Im hoping there is a better way! Thank you.

Re: [osg-users] background color fills all the window (not only the given viewport)
Frederic, I think you can't limit the OpenGL drawing to a limited region of a window HANDLE. You could embed a window in the region you want to use OGL, and just draw to it. Or you could first draw the OGL/OSG code, and then get the window handle and draw all your other stuff using GDI or whatever.

The message is broken, sorry. Hi Ümit, Most of the time, this problem is due to Blender's 3ds import, not osgExport. If you check the vertex count right after the import process, you'll see that the model has already grown. I've experienced two facets of this problem : - 3ds importer doubles the vertices at object level. - Meshes get complicated during the import. Try other formats, try checking if the objects are duplicate, try running the osgconv with --simplify option and one last thing is, you need to search and replace the osgExport script to set data variance flags to STATIC. It passes everything as dynamic and therefore OSG Optimizer leaves unnecessary matrix transformations. I've succeeded in simplifying the models back to their original complexity with these methods.

Should be replaced with
SET(OSGPPU_CONFIG_HEADER ${PROJECT_BINARY_DIR}/include/osg/Config.h)
Since the files of osg/Export include osg/config.h
No?

Re: [osg-users] How to remove the blue background color
Hi Corry, 2009/3/25 Cory Riddell c...@codeware.com Yun's suggestion allows you to replace the blue color with another solid color. If you want an image (I want a gradient), do something similar to osgHUD, except draw first rather than last to put the image behind everything else. The osghud or osgdistortion example are good places to start. You bascially want one Camera to draw the background image, then another camera to draw the main 3D scene. The first Camera will need to have it's RenderOrder to PRE_RENDER and for it to ClearMask so that is clears the depth and colour buffer, then the second Camera to have it's ClearMask set to just clear the depth buffer.

[osg-users] I need your opinion in 3d lighting techniques
Hi, We (www.jct.ac.il) are making a 3d viewer for non-continuous functions in n-dimentions (well there 3d projection to be precise).

Hi Guy, hmm, maybe you confound the Config.h of osgPPU with the Config.h of OSG. These are different things. Currently in osgPPU/Export.h the Config.h is not used at all, hence it shouldn't be any problem when building the osgPPU.

[osg-users] better use smart-pointers or plain pointers in this case?
Hi,
i'm working on a point-in-polygon test. my current implementation has a list
with plain pointers that hold references to the polygons' properties. (i use
them to ease the calculating of an inside-result for that polygons)
Code:
class FetchedPolygon {
public:
FetchedPolygon(osg::Geometry* geom = NULL, osg::Vec3Array* verts =
NULL);
osg::Geometry* geometry;
osg::Vec3Array* vertices;
std::vectorosg::PrimitiveSet* primitiveSets;
};
std::mapconst unsigned int, FetchedPolygon fetchedPolygons;
before, i used smart-pointers to reference the polygons. (of course) it works
both ways, but i can't decide what typ of referencing to use.
i think if i use smart-pointers, i would be able to check if the actual
polygons in the scenegraph are still valid (check the ref counter) without the
need of a dirty flag.
but if the polygons get changed/deleted (e.g. when i want to load a new set of
polygon features) the properties i'm pointing to wouldn't be deleted as long as
the smart-pointers are referencing them.
i think its hard to give a rule of thumb when to use smart-pointers. in general
i'm using them when objects (especially for the scenegraph) are created - as
long as they won't be attached to another scenegraph-object on the next line.
i don't use them to reference these already allocated objects, e.g. when they
are passed to another function, i would use a local pointer inside.
so what your suggestions? Thanks in advance,
christian

Re: [osg-users] Most efficient way to use osg::DrawElementsUInt?
Jesper, I've encountered similar issues when managing 1000's of particle systems (bullet splashes in the water). The problem is the constant allocating/deallocation of memory when you create new primitive sets and then remove them. I ended up caching the primitive sets when the particle system ended and then reusing them. This along with using reserve() to preallocate the required number of elements, resize(0) to reset the element counter - without releasing the memory, and the primitive set setCount() method to adjust the number of prims being drawn each time the particle system was updated. This only works of the things you're creating all similar. It's comparable to what you're doing with the static memory - but within the osg framework. Brian This is a PRIVATE message.

Re: [osg-users] Most efficient way to use osg::DrawElementsUInt?
Hi Jasper, Adding lots of objects in any one frame can easily become a bottleneck unless you are very careful about it. I wouldn't expect the push_back on a DrawElementsUInt to be the primary bottleneck. Make sure you do all your benchmarking in release mode as this makes a huge difference. As to what is your best route forward will depend entirely on what you are actually trying to do in your application, so perhaps you can explain at a high level what these geometries represent and why that have to be introduced on mass on particular frames. Perhaps then others will be able to recommend what the best course of action is to take. Robert. 2009/3/26 Jesper D.

Hi Guy, Guy wrote: Forget it, sorry, I found the files :) The OSG_GEN_INCLUDE is where the CMake generated the solution and the files are there. Yes, the files are there, where CMake generate them, when you build OSG. OSG_DIR is a path, where osg can be found. It can be either an installation path, or just a path where you have downloaded it (because it will look under OSG_DIR/include and OSG_DIR/lib for the osg files). Actually you point out something, which I have to remove from the CMake files of PPU. Since, there is no need in use the OSG_GEN_INCLUDE_DIR at all, I should remove them from the CMake to not to confuse users. Even more, maybe I have to cleanup everything which is non-related to PPU from the cmake files.

Re: [osg-users] better use smart-pointers or plain pointers in this case?
Christian Sam wrote: i think if i use smart-pointers, i would be able to check if the actual polygons in the scenegraph are still valid (check the ref counter) without the need of a dirty flag. but if the polygons get changed/deleted (e.g. when i want to load a new set of polygon features) the properties i'm pointing to wouldn't be deleted as long as the smart-pointers are referencing them. You say that like it's a bad thing. If you use bare pointers, are you ever going to encounter a situation where you have a pointer to something that's been deleted? Using smart pointers (or any RAII wrapper object) is rarely a bad idea. I would be worried however, about overloading the meaning of the reference counter to also indicate dirtiness. I would be tempted to add an isDirty() method. That way you can use a bool or the reference count and can easily change from one implementation to another.

Re: [osg-users] [osgPPU] build osgPPU
Now everything works. I actually needed the OSG_GEN_DIR since it is where the Config files are. I had installed CUDA. It is strange that it didn't find the utils libraries, since all other CUDA related stuff it did found... I'll try to check it. Thanks again! Guy. -- Hi Guy, Guy wrote: Forget it, sorry, I found the files :) The OSG_GEN_INCLUDE is where the CMake generated the solution and the files are there. Yes, the files are there, where CMake generate them, when you build OSG. OSG_DIR is a path, where osg can be found. It can be either an installation path, or just a path where you have downloaded it (because it will look under OSG_DIR/include and OSG_DIR/lib for the osg files). Actually you point out something, which I have to remove from the CMake files of PPU. Since, there is no need in use the OSG_GEN_INCLUDE_DIR at all, I should remove them from the CMake to not to confuse users. Even more, maybe I have to cleanup everything which is non-related to PPU from the cmake files. As to the warning you get in FindCUDA: I have to install CMake 2.6.3 first to check why this warning happens. On my current machine I have versions below that and they don't have any warnings. CUT and CUT_INCLUDE, are the CUDA utils libraries. If you do not have cuda installed don't care about them, since the CUDA example would not be build then.

Hi Cory, Orthographics views don't function like perspective ones, when you move near to the center, nothing actually changes w.r.t your view. This is normal and what you shoudl expect. If you want to simulate a perspective view by moving the left, right, top and bottom values of the projection matrix in then it kinda works, but and this is a HUGE BUT, you then hit issues what to do about the near and far plane. Soon you'll be trying your really hard to just and get get a orthographic view and perspective to kinda work the same but you'll never get to where you want to get to, perhaps some day after a few weeks of trying you might just come to realization that it can't be done, orthographic views just should never be used like perspetive one. So... rather than waste much of your life, and much of our time trying to support you give up now. Learn that orthographic views are best kept for external views of models where the whole model can be seen, or map views where no issues with the near/far planes exist.

Re: [osg-users] zoom and orthographic projections
Sorry for my curt response before -- it was from my cell. Zooming in orthographic projection is not only possible, it's easy, and for an OpenGL implementation example, I'll direct you to the OpenGL Distilled example code: http://code.google.com/p/ogld/. See the Viewing example, setProjection() method. The Viewing example allows you to switch between perspective and orthographic. You can change the alt/az of the eye and zoom(*) in either projection mode. There are good code comments there describing how the code mimics a change in eye distance while in orthographic projection. (*) In perspective, the code allows you to move the eye forwards or backwards without changing the FOV, so this is not a zoom in the strict definition of the word, it is just a camera pan along the view vector. In ortho, on the other hand, it is a true zoom (the FOV is shrunk or expanded), as panning the eye along the view vector obviously has no effect in ortho.

This is normal and what you shoudl expect. If you want to simulate a perspective view by moving the left, right, top and bottom values of the projection matrix in then it kinda works, but and this is a HUGE BUT, you then hit issues what to do about the near and far plane. Soon you'll be trying your really hard to just and get get a orthographic view and perspective to kinda work the same but you'll never get to where you want to get to, perhaps some day after a few weeks of trying you might just come to realization that it can't be done, orthographic views just should never be used like perspetive one. So... rather than waste much of your life, and much of our time trying to support you give up now. Learn that orthographic views are best kept for external views of models where the whole model can be seen, or map views where no issues with the near/far planes exist.

But normals per primitive or per vertex are 'global' for the entire shape. Aren't they? The crease angle is a 'local' feature so that you can have a shape with some smooth and some sharp edges. Can normals per primitive and normals per vertex both be used in a single shape? If not, the only way I can imagine having a shape with some smooth and some sharp edges is if there is one normal per vertex per face. Just like the diagram in the VRML spec shows, if a vertex has 2 faces connected to it, it needs 2 normals for a sharp edge, and either 1 or 2 for a smooth edge. -Ben -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Jan Ciger Sent: Thursday, March 26, 2009 9:08 AM To: OpenSceneGraph Users Subject: Re: [osg-users] VRML Normal Issue -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, Ben Axelrod wrote: Thanks for the info.

Just set the normal binding to be per primitive/face and not per vertex if you want to have sharp edges and define face normals. Otherwise, if the corners/edges are to be smoothed, you use normal binding per vertex and calculate normal as an average of the face normals of the faces adjacent to the vertex.

If the face normals have an angle smaller than the crease angle, the vertex normals will be an average of the two face normals. For sharp edges you will indeed have to duplicate the vertices to accommodate the different face normals (as explained here: http://www.songho.ca/opengl/gl_vertexarray.html) On the other hand, if you want only sharp edges, you can bind normals per face and save yourself this whole escapade. Honestly, it is simpler to export the vertex normals from whatever tool you are using to produce the data than to fidget with the crease angle - it is only a kludge to let the program guess the model author's intentions.

This re-ordering solves the bug without having to do an costly (in time) patching of the quadMap and is more straight forward code was so will be easier to maintain thatn Christophe's patch too. In testing I also found that the svn/trunk version of GDAL's multi-threading warp operation was generating black output images, so I've made use of the single threaded version the default which fixes the black texture problem.

Re: [osg-users] I need your opinion in 3d lighting techniques
Vibrant might be the English word you're looking for...;^) The difference between lighting and no lighting is that you have more coloring to play with. If lighting is enabled, you can play with the materials and normals to give a certain effect, based on some sort of light source. Again, not knowing the data you have at each vertex besides position/dimension info (i.e. temperature, pressure, or whatever) it's hard to determine what would yield the best results or be the most intuitive for what you want to visualize. Perhaps using transparency (alpha in the color) to represent something along with the color for the function may improve things. Lastly, there are always shaders that you can resort to, to visualize your functions. With vertex and fragment shaders, your creativity is your only limitation. Scientific visualization can be somewhat tenuous and it is really an art more than it is a science in giving an intuitive interpretation of the data at hand. I hope I haven't muddied the waters further for you.

Re: [osg-users] How to remove the blue background color
Dear Yun, Corry and Robert, Thank you very much for your help. I tried Yun's suggestion and found that it's the easiest way to do. Just set color to be black and alpha to be 0, and you can have an object floating in the air with augmented display. Best, Dat 2009/3/26 Robert Osfield robert.osfi...@gmail.com Hi Corry, 2009/3/25 Cory Riddell c...@codeware.com Yun's suggestion allows you to replace the blue color with another solid color. If you want an image (I want a gradient), do something similar to osgHUD, except draw first rather than last to put the image behind everything else. The osghud or osgdistortion example are good places to start. You bascially want one Camera to draw the background image, then another camera to draw the main 3D scene. The first Camera will need to have it's RenderOrder to PRE_RENDER and for it to ClearMask so that is clears the depth and colour buffer, then the second Camera to have it's ClearMask set to just clear the depth buffer.

Re: [osg-users] Differences between osgconv at 1.2 and 2.2.0
I'm not sure what this has to do with osgconv? You say you're using the same models. Please explain further why you mention osgconv. If you crank up OSG_NOTIFY_LEVEL, do you get any more enlightening output? Which stage of rendering is the source of the bottleneck on ATI? I assume it's the draw stage. Can you post a .osg model that exhibits the poor performance in osgviewer? Is there a reason you're using OSG v2.2 and not v2.8? Have you tried v2.8 to see if that resolved the problem?

We recently recompiled application using version 2.2.0 version of the libraries and it still flys fine on Nvidia cards, but the frames per second get hammered on ATI cards. I believe it has something to do with pbuffers, because the 2.2.0 compilation returns following error: Failed to create pbuffer, failing back to normal graphics window. Error: Unable to create graphics context - cannot run compression. We use exact same files and models and only difference is the OSG version. Are there any differences in the compiliation command Osgconv?

Re: [osg-users] What about User-Meeting in Europe - osgInEurope?
Hi folks, this is a last reminder about the running poll of the user meeting/conference city. Current state is: Paris, France [ 8 ] Marseile, France [ 0 ] Strassbourg, France [ 1 ] Prague, Czech Republic [ 2 ] Genova, Italy [ 1 ] Brussel, Belgium [ 2 ] Zuerich, Switzerland [ 1 ] Luxembourg, Luxembourg [ 1 ] Munich, Germany [ 0 ] Frankfurt Am Main, Germany [ 1 ] Stuttgart, Germany [ 3 ] I want to join, I do not care about the city [ 3 ] So it seems Paris is the leader, however there are still around one week till the end of the poll (01.04.2009). Make your choice if you interested in this. Next week I will post the results of the poll and we can start to look for the venue and the date in the chosen city.

Re: [osg-users] manipulator design advice
instead of inserting and removing the draggers would a better solution be to use the dragger node masks to select which is visible? Then I could have dragger 1 at root, dragger N a child of dragger N-1, and then the model a child of dragger N. Would you recommended this solution? A followon question: if a nodes mask is cleared so it is not rendered, can it still be intersected?

Re: [osg-users] importing shaders
hi, That is encouraging to know OSG supports shaders natively (now I saw the shader examples). I have got the 3DS exporter working now. Out of 133 examples I can only find 6 that use CompositeViewer at all Just 6/133 - I take that criticism back then! Many of the examples I looked at coincidentally supported a composite view.

[osg-users] FLTK2 port of osgviewerFLTK
As part of something I am working on in school, I needed to use an osgViwer::Viewer inside of an fltk2 GlWindow. I modified / updated the existing example osgviewerFLTK.cpp to work with the most recent svn version of fltk2. The code is included with this email, hopefully all that you should have to do is change the library dependencies in your build process and it should build without error. For the record, here is the string I needed to make it build: g++ osgviewerFLTK.cpp -losg -losgViewer -losgDB -losgGA -lfltk2 -lfltk2_gl -lX11 -lXi -lXinerama -lXft -lpthread -lm -lXext -I/usr/local/include -o osgviewerFLTK If you want the changes, feel free to use them, they built okay on my machine with the latest svn version of fltk2.
