Hello - I have been searching everywhere the last several days for info on projective texturing. I can''t seem to find ANYTHING! I would appreciate it if someone could explain in depth how to accomplish this in Direct3D and provide source code demonstrating the process. The main problem I am having is projecting a texture from somewhere other than the camera. Thanks for your help. - DXMan

the only way i got projective texturing going in d3d was with vertex shaders. it was a long time ago and i lost the code to it, but i still know how to do it.
im thinking of writing a tutorial on it since this topic does come up a fair bit and not many people have an answer for it.

If you go to the Nvidia developer site you can find several articles and code samples there.
