[osg-users] osgCompute - using 32bit osgCudaTexture2D

2010-05-12 Thread Diana

Hi,
I try to make some changes to the osgTexDemo example to use 32bit
osgCudaTexture2D.
I changed the source type to GL_FLOAT, and modified the kernel accordingly
(float4* instead of uchar4*).
The resulting values in VBO were precise (32bit precision), but the values
in trgTexture still had 8bit precision, like in the original example.

Am I doing something wrong?

Thanks a lot,
Diana

 Did you try valgrind, maybe it can spot a problem?
 


I haven't checked it yet. If you could check it under your system it would be 
great. Thanks in advance. Just load basic model cow.osg with osgviewer for 
example and see what 'top' reports.

Re: [osg-users] CEGUI rendering with black windows...

Robert, 
you should rather set the state of the node where CEGUI drawable is attached 
and set it's state like this:

Code:
node-getOrCreateStateSet()-setMode(GL_LIGHTING,osg::StateAttribute::OVERRIDE 
|osg::StateAttribute::OFF);

Re: [osg-users] Shrink/Enlarge whole osg::Groups ?

2010-05-12 Thread Ku Krapox

Hi,

Thanks for your response, and you're right, I'm not as clear as I thought...

Let me explain what I want : I have a scene with an osg::Cylinder that 
represents a tray, and complex objects placed upon it (typically some Groups 
containing Text, Geometry and Shapes...).
Everything is in a PAT and I just want it to be displayed bigger or smaller, 
with the same proportions, without changing its content and with the rest of 
the scene keeping a fixed size.

So from what you say, I understand I should use the setScale method?
If so, how do I set the Vec3d parameter?

Thank you!

Cheers,
Ku

Re: [osg-users] Array of points of object

2010-05-12 Thread Tomlinson, Gordon

Roughly you do this

Create a node visitor

Apply the visitor to the Root node of your object

When you get to a Geode

Retrieve it Geometry/Drawables Nodes

From the each Geometry you can retrieve the Vertex arrays ( what the
pints mean depend on that your using, tri-strips, polygons, tri etc )



See the examples and their code on more info on Node visitor and how is
geometry is created and search the mail archive for more info as this
has come up a few times

[osg-users] [osgPlugins] [VRML plugin] Performances issue ...

2010-05-12 Thread Tangi Meyer

Hi All,

I've been adapting/updating a software from:
- OSG 2.0.0 + Coin 2.5 + IV plugin + Visual C++ 2005 
to
- OSG 2.9.5 + OpenVrml0.14.3 + Visual C++ 2008.

There seems to be a serious drop in performances with the newer version 
regarding the loading of vrml files through the following call:
osgDB::readNodeFile(Filename)

Is it the case or do you have an idea of where I should look?

Thank you very much in advance!

Re: [osg-users] [osgPlugins] [VRML plugin] Performances issue ...

Hi Tangi,

Try converting the orignal database into an .osg file using osgconv i.e.

  osgconv myfile.iv myfile.osg

Then compare the performance when handling the .osg file between the
two versions.  This will tell you whether it's the OpenVRML plugin
creating a different database as the cause of the difference of
something else in the build.

Also please do all testing with a release build of the OSG as
debugging information totally destroys performance, and just how badly
it affects performance with differ between VS 2005 and 2008.

Robert.

Re: [osg-users] Problem with derived class from osg::Drawable

Hi Saravanan,

The compiler is telling that you haven't implemented methods that you
must implement as they are defined by the abstract base class.  In
this istance you haven't implemented the clone methods that you need
to.  There is a convenience macro to help you out.  Please look at the
ShapeDrawable or Geometry headers to see how the macro is used.

Robert.

[osg-users] problem with osgUtil::IntersectVisitor and osg::LineSegment

2010-05-12 Thread Olivier Martinaud

Hi,

I'm having some trouble implementing an intersection detection method. I have a 
model of a building and I'd like to get the coordinates of the intersection 
points between the model and a ray. I wrote the following code from osg samples 
online. 

osg::LineSegment  *ls = new 
osg::LineSegment(osg::Vec3d(-5,-5,-5),osg::Vec3d(5,5,5));
osgUtil::IntersectVisitor *iv = new osgUtil::IntersectVisitor();
iv-addLineSegment(ls);
iv-apply(*m_node);
std::cout  iv-getNumHits(ls)   intersection points (hits).  
std::endl; //result = 6
osgUtil::IntersectVisitor::HitList hitlist = iv-getHitList(ls);
std::cout  size :   hitlist.size()  std::endl;
//std::vectorosgUtil::Hit::iterator itr = hitlist.begin();
hitlist[0].getWorldIntersectPoint(); //causes unhandled exception...


When I execute the code I have this error : unhandled exception at 0x100042aa 
in OSGDefaultProject.exe : 0xC005: access violation when reading 0xfeeeff36.
The problem comes from the last line of the  code 
(getWorldIntersectionPoint()). What's weird is that the iv finds 6 points of 
intersection, so the algorithm seems to work fine. But the size of my hitlist 
is abnormally large : it says more than 4 billion !


Thank you!

Cheers,
Olivier

The isosurface shader in osgVolume does the compute of the isosurface
purely on the GPU for fragment, the only end result is the colour of
the final fragment, no information is passed back to the CPU, and no
mesh generated at any stage.

 Subject: [osg-users] problem with osgUtil::IntersectVisitor 
 andosg::LineSegment
 Sent: May 12, 2010 7:02 PM

 Hi,

 I'm having some trouble implementing an intersection detection method. I have 
 a model of a building and I'd like to get the coordinates of the intersection 
 points between the model and a ray. I wrote the following code from osg 
 samples online.

        osg::LineSegment  *ls = new 
 osg::LineSegment(osg::Vec3d(-5,-5,-5),osg::Vec3d(5,5,5));
        osgUtil::IntersectVisitor *iv = new osgUtil::IntersectVisitor();
        iv-addLineSegment(ls);
        iv-apply(*m_node);
        std::cout  iv-getNumHits(ls)   intersection points (hits).  
 std::endl; //result = 6
        osgUtil::IntersectVisitor::HitList hitlist = iv-getHitList(ls);
        std::cout  size :   hitlist.size()  std::endl;
        //std::vectorosgUtil::Hit::iterator itr = hitlist.begin();
        hitlist[0].getWorldIntersectPoint(); //causes unhandled exception...

 When I execute the code I have this error : unhandled exception at 0x100042aa 
 in OSGDefaultProject.exe : 0xC005: access violation when reading 
 0xfeeeff36.
 The problem comes from the last line of the  code 
 (getWorldIntersectionPoint()). What's weird is that the iv finds 6 points of 
 intersection, so the algorithm seems to work fine. But the size of my hitlist 
 is abnormally large : it says more than 4 billion !

 Thank you!

 Cheers,
 Olivier

Re: [osg-users] osg latest developer release, memory leak under linux

Hi Mathias,

2010/5/12 Mathias Fröhlich m.froehl...@science-computing.de:
 It therefore seems there is a leak in the mutex code path for atomic in
 OpenThreads. I don't have time to investigate further.
 The attached patch helps a lot for this problem here.

 Robert,
 Do you need a correct osgsubmission for that?

In this instance I've applied the patch, and checked it into
svn/trunk.  However, in general keep the submissions as whole files
and posted to osg-users as the chances of me missing submission that
are sent to osg-users is very high - it's easy to loose a needle in a
hay stack.  Posts to osg-submissions are all about submissions so are
the reliable way.

This issue also suggests that Cmake isn't handling the g++ version
under Fedora 10 for some reason and is not enabling the atomic ref
counting.  I didn't think Fedora 10 was that old that it wouldn't
support atomic ref counting.

Thoughts?
Robert.

2010-05-12 Thread Serge Lages

Hi Art and all,

I am coming back on this subject because I am currently trying to use osgPPU
with osgShadow.

I've followed this thread instructions and it works, but only with the
ShadowMap
technique, and the one I prefer is MinimalShadowMap. With this one, combined
with HDR, it  renders all my scene in white... Any idea on what to do ?

Thanks !

 I do not realy understand what you mean here with giving osgPPU the same
 node as for shadows. osgPPU doesn't now anything about the graph, it does
 only get camera as input, hence use the camera color buffer texture as
 input. Therefor the camera, which is connected to the osgPPU, which can be
 your main camera or some other one, should be able to render your shadowed
 scene.

  After seeing what you did in your correction I
  rearranged the graph
  like this:
 
  scene-addChild(shadowedScene);
  shadowedScene-addChild(loadedModel);
 
  and everything worked as expected.  Now I just want to
  understand why this
  worked.  It it because osgPPU and osgShadow are no longer
  fighting to control
  the state of the single scene node?

I can see three possibilities:
* Your compile flags containe -march=i386 or (may be this is also sufficient 
to trigger this, -march=i486).
* The compiler you used is may be hand compiled and has a default architecture 
of -march=i386.
* The gcc in fedora 10 has still a default instruction set architecture 
of -march=i386.

True?

Each of which prevents gcc from using the the required atomic assembly 
operations which are only available if gcc runs with -march=i486 or newer. 
Consequently the 'last resort' Mutex is used.

RHEL 5 has the same behavior.  Unless you explicitly specify -march=i686 
(or something similar) for CFLAGS, it fails to detect GCC builtins.  It 
hasn't been a big problem for me, so I just chalked it up to RHEL 5 
being past its prime.

The Vec3d parameter specifies the scale factor in each direction, so

It's not the wrong way of posting, it's the wrong way to send an email. You'd 
be best off breaking that habit before you send the wrong thing to the wrong

 Why do we need 120 hz for stereo rendering for visual simulation applications 
 ?

120 Hz is used for frame sequential formats, and gives you full 60 Hz 
information to each eye. Without full 50-60 Hz, motion isn't as smooth without 
using expensive techniques like motion blurring. It's especially true for frame 
sequential stereo 3D, since you'd also get unpleasant flickering at lower rates.

More to the point, this has become somewhat of a standard in projectors - it's 
close to the current limit of dual-link DVI (at 1920x1080) and fast enough to 
avoid artifacts.

[osg-users] problems with EventHandlers, slave cameras and CompositeViewer

2010-05-12 Thread Stephan Maximilian Huber

Hi,

I have some problems with a complex display-configuration utilizing
slave cameras and a composite-viewer. Here's the basic setup:

1 compositeviewer handling one view which has only one camera, no
graphicscontexts and 4 slaves. Every slave renders into its own
graphicscontext, representing a window on a screen. (I know I can use a
single viewer for this scenario, but unfortunately i'm bound to
compositeviewer, because i need multiple independent views)

This setup works, despite the trackballmanipulator isn't usable, only
the scroll-wheel gets handled. After debugging the inners of osgViewer +
osgGA the problem lies in resetting the input range of the current
eventstate to -1..1 (compositeviewer.cpp, around lines 778 and 807),
which results in wrong calculations for getXNormalized() and
getYNormalized().

I commented out the two lines in compositeviewer.osg and now my setup
works without problems, but before sending a fix to osg-submissions, I
want to ask what's the intent of resetting the inputrange of the event
state?

Perhaps I should modify the osgcompositeviewer-example to show my
usage-pattern, I'll do that if requested.

Thanks for any input,

cheers,
Stephan

Hi Martin, thanks for your reply but I am talking about another problem.

 

The problem with osgShadow + Seven/Vista + fullscreen = black screen is
pretty familiar to me, but I always disable aero on final setups so it's not
a deal.

 

My current problem is with osgShadow::MinimalShadowMap and osgPPU, my scene
becomes white, but it works with the osgShadow::ShadowMap technique.

 

Cheers,

Hi,

 Awesome, thanks for the correction.  I see that my initial
 example forgot to
 actually add the model to the shadowed scene :P  But that
 wasn't the real
 problem.  The real problem was giving osgPPU the same node
 that i was using for
 shadows.
I do not realy understand what you mean here with giving osgPPU the same
node as for shadows. osgPPU doesn't now anything about the graph, it does
only get camera as input, hence use the camera color buffer texture as
input. Therefor the camera, which is connected to the osgPPU, which can be
your main camera or some other one, should be able to render your shadowed
scene.


Cheers,
art


 After seeing what you did in your correction I
 rearranged the graph
 like this:

 scene-addChild(shadowedScene);
 shadowedScene-addChild(loadedModel);

 and everything worked as expected.  Now I just want to
 understand why this
 worked.  It it because osgPPU and osgShadow are no longer
 fighting to control
 the state of the single scene node?

Re: [osg-users] problems with EventHandlers, slave cameras and CompositeViewer

Hi Stephan,

Modifying/creating an example that recreates this issue would be useful.

The handling of event ranges is an awkward one as the code has to
handle a range of different usage models.  The use of non dimensional
coordinates is one of the techniques that osgViewer uses to get round
issues of sharing a single view over multiple cameras, as is the
reprojection of the mouse coordinates into the eye coordinates of the
master camera.   Given the complexity of what it's trying to do just
hacking code out is mostly likely to fix one case and break half a
dozen other cases so I'd be very wary.

Robert.

 Hi,

 I have some problems with a complex display-configuration utilizing
 slave cameras and a composite-viewer. Here's the basic setup:

 1 compositeviewer handling one view which has only one camera, no
 graphicscontexts and 4 slaves. Every slave renders into its own
 graphicscontext, representing a window on a screen. (I know I can use a
 single viewer for this scenario, but unfortunately i'm bound to
 compositeviewer, because i need multiple independent views)

 This setup works, despite the trackballmanipulator isn't usable, only
 the scroll-wheel gets handled. After debugging the inners of osgViewer +
 osgGA the problem lies in resetting the input range of the current
 eventstate to -1..1 (compositeviewer.cpp, around lines 778 and 807),
 which results in wrong calculations for getXNormalized() and
 getYNormalized().

 I commented out the two lines in compositeviewer.osg and now my setup
 works without problems, but before sending a fix to osg-submissions, I
 want to ask what's the intent of resetting the inputrange of the event
 state?

 Perhaps I should modify the osgcompositeviewer-example to show my
 usage-pattern, I'll do that if requested.

 Thanks for any input,

 cheers,
 Stephan

[osg-users] Develop for XP/Vista/Windows 7

2010-05-12 Thread Martins Innus

Is it possible to create a single OSG application that runs on XP, Vista 
and Windows 7?  I develop under VS2003 on XP and create an installer 
package from within VS that has all the dll's and main exe in one 
directory. Until now we have only run our software on XP, but we just 
had a user try to run on Vista and our application ran, but without 
textures and a much lower framerate.  I'm waiting to hear back if there 
was anything printed to the console, but I don't have a Vista machine 
locally to test on.  I know this is sparse on details, but I'm just 
curious to know if this should work.


I'm assuming there are OSG developers who've done this.  I can upgrade 
Visual Studio if necessary.


Thanks for any insight.

Re: [osg-users] Uniform scale dragger?

2010-05-12 Thread Gary Robinson

Hi,

I've just run into the same thing. I ended up changing the osg source code for 
the Scale1Dragger to get it to change all axes uniformly. This can be done by 
changing the Command header file in the osgManipulator project. Inside the 
declaration of the Scale1DCommand class, there is a function called 
getMotionMatrix(). The second line in that function (line 226 in that file for 
me) applies a scale in only 1 axis, you just need to change it to apply the 
same scale to all axes. So, change the line:

* osg::Matrix::scale(_scale,1.0,1.0)

to:

* osg::Matrix::scale(_scale,_scale,_scale)

and the Scale1DDragger becomes a uniform scale. Recompile the osgManipulator 
project and use your recompiled dll in your application.

I'm thinking about perhaps making a separate class for Scale3DDragger, for 
example, that would be the uniform scale and submitting it to osg to include, 
but at the moment I don't want to take the time. Perhaps adding an option to 
the ScaleAxisDragger to make it uniform if desired would be better. Good luck 
in the meantime.

Thank you!

Cheers,
Gary

Re: [osg-users] Develop for XP/Vista/Windows 7

2010-05-12 Thread Jean-Sébastien Guay


Hi Martins,


Is it possible to create a single OSG application that runs on XP, Vista
and Windows 7?


There is nothing in the OS itself that will prevent this, we do it all 
the time (we develop mainly on Vista and Win7, and our installers 
install and run correctly on Vista and Win7 obviously, but also on XP).


You have to be careful with some things, like manifests and runtime 
versions. In their great wisdom, MS sometimes only releases some 
security fixes for Visual Studio (which alter the runtime version) on 
some of the platforms, not all - a recent ATL security fix comes to 
mind. These may prevent the software from running when the target 
machine has an older version of the runtime installed, but generally 
wouldn't result in missing textures or slower performance...


Some of these things have been discussed on this list in the past, 
search the archives.



Until now we have only run our software on XP, but we just
had a user try to run on Vista and our application ran, but without
textures and a much lower framerate.


With nothing else to go on, I would suspect outdated drivers or a bad 
video card rather than it being Vista causing the problem. As I've said, 
we've used many flavors of Windows without too many problems.

2010-05-12 Thread Chuck Seberino

Pawel,

You can always do something like this:

make VERBOSE=1

from the command-line when building to see the details of what CMake is doing.  
You can then see what flags are being passed to the compiler.

Missing textures and slow frame rate sound a lot like old ATi drivers to

Re: [osg-users] [Solved] OSG and CEGUI 0.7

2010-05-12 Thread Wood, Alexander B

I haven't looked into window resizing with CEGUI yet, but I did submit
some code to osg-submissions that has a working example of interfacing
OSG 2.9.7 with CEGUI 0.7.1, so you can refer to that submission (still
pending review) for a complete example.

To correct the mouse cursor, you need to do the following in the
CEGUIEventCallback::handle:

float x = ea.getX();
float y = ea.getY();

// CEGUI wants 0,0 in the top left corner; osg has 0,0 in the bottom
left corner
y = ea.getWindowHeight() - y;
