Hi,
I got a (sporadic) MS VC Runtime Error (MS VS 2008, Config RelWithDebInfo) in
OSG 2.9.9 as follows. The file was created with:
Code:

Callstack of the runtime error:

Hi,
I use VRJuggler and OSG to create an application on a VR system and I want to
use osgWidget. But VRJuggler uses osgUtil::SceneView instead of osgViewer, I
wanted to know if it is possible to use osgWidget with osgUtil::SceneView?
Thank you!
Cheers,

Hi,
I'm not very experienced with shaders and I'm trying to write a reflection
shader for the cubemap exemple.
I tried to compute the normals and so on, but I don't get the result I'm
expecting.
Do have someone a shader (and the modified c++ source code) that is working in
this demo ?
Thanks
Thank very much!

If you build your models in Maya, you can try the Maya2OSG exporter in
http://maya2osg.sourceforge.net
Texture coordinates and texture transformations are exported to OSG file.
Best regards,
Javier Taibo.

Hi,
Is this the correct way to do it?
Remove all textures from a StateSet:
ss->getTextureAttributeList().clear();
ss->getTextureModeList().clear();
Remove all texture coordinates from a Geometry:
geometry->getTexCoordArrayList().clear();

Hi Florian,
Does the problem exist when using models form the standard
OpenSceneGraph-Data set? i.e.
osgconv cow.osg cow.ive -O compressed
I have just done this test on my Linux system and it works fine, and
I'm able to run "osgviewer cow.ive" just fine.
FYI, very little has changed with the .i

I have never personally attempted to do these specific steps, but I

Hi Jordi,
I think the problem is in this line of code in your vertex shader:
vec4 pos= gl_Vertex+
vec4(texture1D(texturePos,(float(gl_InstanceID)/nInstances)).xyz,0.);
I think that texels are placed in the [0..1] range using their centers
and not the left edge as your code assumes. That means
Hi Juan,

OK, this works for me, I could do a submission at some point.
My knowledge is:

2. don't invert for Google SketchUp >= 7.1
3. findInvertTransparency does not always yield correct results
Something along the lines (code for determining version not included):

Hi Jeremy,
In fact, I had always lamented the WindowManager's need for a View

I can look at replacing this dependency with manually running an

Hi @ all,
i have a question about the use of a plugin after it was build.
Do I have to rebuild OSG in some manner or how do I notify
OSG that there´s a plugin?
In my case I need the collada PlugIn.
Thanks in advance.
Cheers,
Tomas

Hi,
Thank you Jean-Sébastien for your devices.
Indeed, I put the WindowManager's ortho camera under the root of my scene
graph. With VRJuggler, I can't access to the cameras because the cameras aren't
included in the scene graph. So I don't know how to do this.
Would you have other suggestions?
You have to build and its dependencies

Here's what I would do to start:

Attached is a simple stripped down app that demonstrates the problem.

Hi,
So this issue (and many others) arises from the GL.h file that QT installs in
place of the default windows version. Reverting to the "vanilla" GL.h file
fixes it. Does anyone understand why QT does this and are there any tips for
making QT play nice with OSG?

I've sent this e-mail to osg-users@lists.openscenegraph.org but I didn't

Hi,
I've also been experiencing the fullscreen issue with nVidia cards on
Windows 7. Just wanted to let you know that I found a workaround.
When creating the OpenGL context, I changed the swap method
from WGL_SWAP_EXCHANGE_ARB to WGL_SWAP_COPY_ARB. This completely solved the
issue for me.
