Texture Mapping source code...

I want to get source code of texture mapping in Win32.

<requirement>
source code have to be programed in C.
mapping speed have to be fast(optimized code).
program have to run in Win32 API.
example must be included..

thanks.

BlackMan, thanks for your comment
but I don't want Direct3d, OpenGL, Guild etc..
I do not need source code with 3D library ..

I want raw algorithm of texture mapping .

kinkajou

True texture mapping onto a polygonal object? As opposed to just bitmapping.
