[Bf-committers] Cycles and voxel data texture?

[Paul Melis]

Sorry, but your comments don't make things much clearer to me. Do you 
mean that general VoxelData textures can be used in smoke domains (but 
with limitations)? I'm interested in rendering of general 3D volumes of 
(scientific) data, not in smoke or fire.
