In openscenegraph-3.0.0/OpenSceneGraph/src/osgVolume/RayTracedTechnique.cpp the 3D texture is being clamped to a border color of (0,0,0,0).
It seems to me this should be CLAMP_TO_EDGE rather than CLAMP_TO_BORDER, since using a border color not in the actual texture is completely arbitrary. I'm using my own shaders and seeing a lot of unwanted effects from this border color, such as unwanted color darkening and inability to define my own alpha mapping. What do you think? I don't see how it would cause any problems.
