Hello Hello to NeHe Love your stuff, will help you as soon as I can I''m in the process of designing a 3D engine with OpenGL for BeOS and Windows. I''m looking for procedurals textures, which are great stuff (very nice for 3d textures [solid texturing]). But I don''t know how to access a surface texture or to do to build my procedurals textures. Do I have to create a BMP and pass it to OpenGL or can I do it with OpenGL directly ? -* Sounds, music and story makes the difference between good and great games *-
