Hi, again! Is there any good link or a simple explanation of how to do DOT3 bumpmaping using normal maps? (It is supported on GF2, isn''t it?)

see ATI developer site, there''s a simple dot3 exemple with source code

http://www.ati.com/developer/indexsc.html
see upper right corner and click "RadeonSimpleDOT3"
It uses 2(or 3 if you count multitexture) OpenGL extensions, env_combine & env_dot3.

There are some very nice articles on the nVidia developers site too on DOT3 bump mapping...

Death of one is a tragedy, death of a million is just a statistic.
