However, one thing still intruiges me: Karlos, what are voxels? At some point, in the early 90's, German magazines were aflame with them. They would be the Next Big Thing, but apart from two games, the concept never took off. I know a pixel---picture element---and the texel---texture element, usually triangular. Voxel implies something with volume, but volume rendering is a slow and painstaking process. (At leaat, on the data visualisation programs I use.) Could you be so kind as to elaborate?
I don't know much about them, but I do know that DeltaForce (1 and 2) used a Voxel engine, which actually gave very good results. DetalForce 3 used a standard Polygon engine, so that it could use DX/GL... the graphics didn't look so good them.
