Some users do implement look up tables using 1D textures and fragment program or TexEnvCombine, and the OSG does support all these elements, so if you want to do DIY colour tables is not difficult to do. This is something that users doing volume rendering will typically do.

Has anyone used OSG with texture and/or colour look up tables?
I can't seem to find any obvious references to them in either the OSG documentation or the example code. Are they supported?
