Hi Robert, My program was using coin3D for volume rendering before. Now it is replaced with osg, but I still want the existing machine is able to run osg version. Last time you mentioned it is possible to implement a crude 3D volume rendering based on 2D textures. Can you tell me more in details how to do? Do you mean the current osg doesn't have this feature? Is it required to modify the source code and recompile again? Thanks.

Volume rendering is one of most challenging tasks for any graphics card to handle, it tougher than *any* game available, it pushes the memory bandwidth and capacity to the limit, it can brings high end hardware to it knees. Yet you are trying to get things working on crappy Intel embedded graphics and virtual machine. You really need to reset your expectations. Volume rendering requires decent graphics hardware. Is not the osgVolume doesn't support crappy graphics, it's that crappy graphics doesn't support volume rendering.
