Hello to all,
googling around (and yahooing to be politically correct…) I realized how difficult it is to find sample applications that demonstrate some practical use of 3D textures, so here I am with a very simple question: in your experience, why do we need 3D textures and what can we use (or abused) them for?
3D textures get used a lot as 3D noise lookups.
Terrain texturing is also a possible area of use.
Nice soft shadows, too. (but the preprocessing is slow). A 3D texture was used as the volume of light. There’s a demo, I don’t remember where.
Any time you’ve ever written
value = table[i][j][k]
is an application for 3D textures.
Thank you guys for your replyes, it was enlighting
