Hi,
I think this issue is related to latest OSG. I'm using quite older card ie
3dLabs wildcate 7210. I tried the terrain on different pc with Nvidia card and
there is no issue there. Sorry for posting here.
Thank you!
Cheers,

Hi everyone,
I have some question about render to texture. The code that I give below is
work but I have some question.
1. Why I have to use viewer.frame() for 2 time for working ?. If I use
viewer.frame() just one time it doesn't work. The written image show just
bank screen.
2. How to run

Hi,
I have found a problem building osgCompute in Ubuntu 10.04 with
CMake 2.8. My knowledge about CMake is near zero, so I cannot give
much more info than the error I get:
CMake Error in examples/osgGeometryDemo/src/CMakeLists.txt:
Cannot find source file WarpMe.vsh. Tried extensions .c .C
I think you need the data from separate osgCompute repository.

Silly me!!! I had the data and the OSG_FILE_PATH env var set, but I
missed the OSGCOMPUTE_FILE_PATH.
Thanks for the hint! (and sorry for the noise :)

Hi,
I'm newbie to OpenSceneGraph and I'm developing an application which supports
2D animations over quads. The idea is apply a texture over each quad, and
update its texture coordinate array, using a cull callback.
MatrixTransform - Billboard(CullCallbakc) - DrawableQuad(texture)

have you tried sharing a context between the views? I'm not very
familiar with stereo, but my guess would be the context of the second
view is not set for stereo.

Hello J.P.,
both cameras have the same graphics context (gc). Here the complete part of the
code with the views:
osg::ref_ptr osgViewer::View view0 = new osgViewer::View;
view0-setSceneData(root);
view0-setDisplaySettings(ds0);
view0-getCamera()-setViewport(500,0,500,800);
Hi,
OK, I saw this
traits-sharedContext = 0;
We normally have something like this:
if (this-getNumViews() = 1) {
traits-sharedContext =
this-getView(0)-getCamera()-getGraphicsContext();
}

I get the same errors, I think it has to do with why you can only save to

Hi,
I noticed the problem with first call of viewer.frame() too. This is happens.
because meanwhile the viewer initialization - which is called by first call of
viewer.frame() - a call to glGetString (SceneView::init() -

Hi, thanks everyone here to give me the ideas...
I will try matching Cube GPU with OSG.
Geomtery shader with OSG i think is the best solution.
isn't it?

Hello,
Every day a new problem. :-)
Ok, so my Render To Texture works, but my shadows are not visible in the
texture (rendertarget).
My Settings:
rtt_cam-setRenderOrder(::osg::Camera::PRE_RENDER, 0);
rtt_cam-setRenderTargetImplementation( osg::Camera::FRAME_BUFFER_OBJECT );

Hi Dietmar Funck
Thank you very much for your reply. Do you mean, the first viewer.frame() is
used for initialization that why nothing is rendered in the first frame ?.

Hi, Dietmar Funck.
In order to get another texture attached you can use something like
_cam-setCullCallback( new fboAttachmentCullCB( this ) );
void fboAttachmentCullCB::operator()(osg::Node* node, osg::NodeVisitor* nv)
{
osg::Camera* fboCam = dynamic_castosg::Camera*( node );
Maybe your problem is related to the fact that Shadow maps are usually
stored in DEPTH_BUFFER (not COLOR_BUFFER).

OK, you are right, but that is not my problem. I don't want the shadow texture,
which need the DEPTH_BUFFER. I want the final rendering in my texture.
The basic graph looks like this:

rtt_cam (the result has no shadows)

shadowedScene (with StandardShadowMap)

Hi Michael
Thanks for the info, do you know why I might be having trouble saving these
to .ive, .osg, .osgt and .osgx. It's not a show stopper but for some reason
I can only re save the imported fbx as .osgb. The rest fail to load except
.osg which loads but won't play my animations anymore :(

Hi Shane,
Today I spent a lot of time in reading CIGI documentation and playing with the
MPV and HE. Am I right that CIGI is a framework to organize and standardize
date formats and query formats, but it does not provide the final network
communication functions?
Thank you!

Eric,
You should look at your TexEnv parameters. Use something like DECAL or
REPLACE. Looks like you are using the default, which is MODULATE, which takes
into account the color of the polygon with the texture. Of course these modes
(DECAL,REPLACE) will disable any lighting that is going

I know that the imagestream is playing, because I can see the 'resize'
