Hello
I'm working on a project for my masters degree. I need to do some
volume visualization of data, and the best way to do it is to use 3d textures.
First I tried the example program from the Red Book. It is VERY slow (maybe 1
frame every few seconds), although it seems to work. I also tried the siggraph '99
example - vol3dtex. It displays a skull .... also very slow. The vol2dtex works
great, but of course this is not what I need to do. I guess I would assume that 3d
texturemaps are not supported by Nvidia on TNT2 under linux, except that I had
heard that Quake III uses 3d textures for lightmaps. I have quake III on this
machine, and it runs great (with lightmaps).
If anyone has any idea about what I (and these demos) may be doing wrong, or if
you need more info to help, please either respond here or email me at
wade@pacific.mps.ohio-state.edu
Thanks in advance,
Wade Lutgen
