Thanks Wang Rui, I had a look at the effectscompositor code but I wanted to start with something simpler at first so I went to your cookbook.
I followed the NVG example from chapter 6 of your cookbook in order to create a render to texture camera to write the scene to, then a hud camera to read from the fbo and write to the screen. I think this is the basic framework that I need in order to proceed; now I think I just need to figure out how to create an OpenCL context using the existing osg OpenGL context so that I can operate on the RTTCamera's FBO before it gets read by the hud camera and sent to the screen. I saw this post (http://forum.openscenegraph.org/viewtopic.php?t=11332) about creating an opencl context from osg's opengl context but it's a little vague so I'm looking now for a more complete osg OpenGL-OpenCL interop mode example (if such a thing exists) ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=51893#51893 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
