No, not a good idea. Why? Only 1 card support 3D textures, and those textures require a massive amount of memory.

The GeForce3 supports 3D textures And I bet some of the high end ones will as well 3DLabs(thay still around?), sgi ect... but he is right it takes a lot of mem and is not the best way to go(IMHO).

I would guess nVidia''s GeForce3 should be able to do this as they have the most advanced technology(However TrueForm would have been nice). Yes I am an nVidia Fan, my only non-nVidia 3D-Card was a VooDoo3 and I regret it!


Yesterday we still stood at the verge of the abyss,

Only one? Pff, yeah right. Lets see here: A few 3DLabs cards support it, the GeForce3, the Radeon, the Radeon 7500, the Radeon 8500, and about a handful of others.

I have a wildcatII 5110
so it can definitely do it.
It even supports 4d textures what ever they
use them for.
There are some examples for
ati cards as well.
They use it to look at medical data.

I just looking for some more info.

The reson it would be so helpful is because I could use
it to look at the surfaces generated by the marching cubes algo
but also use it to look at slices through the data.

To the original posters'' point using 3D textures would not eliminate the need for the marching cubes algorithm as you''d still need to calculate faces on the "blob". I don''t see how using a 3D texture improves the situation at all. Maybe it''s just me though. Care to elaborate pacrugby?
