Have a look at IDirectFBSurface::TextureTriangles(). I haven't tested it for a while on a CLE266, but it's working great on Matrox now.
The vertices and texture coordinates for such a rotation are fairly simple.
Ah, thanks! The df_texture demo is very promising and works perfectly on the
CLE266. Now I better get some 3D skills, the ve.c source is hard to
understand due to all the matrix math. Any idea where I could get a start at
reading up on what for example W, S, T coordinates mean in DFBVertex?
Hmm, I don't even see how a rectangle is drawn in df_texture, if the entire 3D
system works with triangles. 3D newbie for sure..
If you find some material, please let me know as well. I could use a tutorial on the 3D beginnings and the vertices etc...
