Shadow map using depth shadow map

love to help, but as much as anyone wants, none of us are superheroes. we need to ''see'' more info to help

developer.nvidia.com have some info on this, and the Game Programming Gems series of books contain a few articles as well. There might also be some articles on this site.

which Game Prog. Gems ??
I own three of them, but I haven''t look them up thoroughly..

It is/they are in the first book - the one I''ve lent to a friend at the moment so I can''t tell you which article(s) exactly . GPG2 contains some stuff on priority buffers (which are similar) and a short discussion of depth shadow maps in articles 4.10 and 5.6.
If I remember correctly, the nVidia papers were pretty good though, so you''ll definitely want to check them out, I''ve found most of them for you:
Hardware shadow mapping
shadow mapping
OpenGL shadow mapping
Direct3D shadow mapping
