Hi Alex, The osgVolume::MultipassTechnique supports mixing geometry with the volume and constraining to a convex hull geometry. This is what you should use instead of FixedFunctionTechnique, the only reason to use this now is that you've have completely hopeless hardware+drivers that are incapabl

Hey all, >From previous posts, I understand clearly that FixedFunctionTechnique is the worst of the osgVolume techniques in terms of both speed and quality of results. However, due to some specific requirements of the application I'm trying to build (need for clipping to a bounding box, need to i
