You might want to explore using vertex shaders to achieve some kind of fake "geometry instancing". The SDK sample "osgforest" does something similar to project a forest made of thousands of trees using GLSL (and also ARB fragment program in the 2.9 branch).
More about OpenGL pseudo instancing is found here in this nVidia paper: http://download.nvidia.com/developer/SDK/Individual_Samples/DEMOS/OpenGL/src/glsl_pseudo_instancing/docs/glsl_pseudo_instancing.pdf Christian _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
