Since you posted in the DirectX forum aswell, I'm guessing you have the DX SDK installed. Check the help files, it includes descriptions of the equations governing PRT and also references to articles on the subject. Or you could just google for it. Beware though that it's a quite complicated subject, if you are attempting to implementing it on your own make sure you have a firm understanding of the mathematics.
