RE: [Algorithms] Current state of shadow maps?

[Siddharth H. <gda...@em...>]

Hi,

 

I tried to do specular mapping using pixel shaders 1.4 and the NHHH mapping method used in http://www.ati.com/developer/R8500PointlightShader.html This seemed to work, but with few minor problems. Before I solve these problems I would like to know the theory behind NHHH mapping. I tried to do a google but with almost nothing. Does anyone know a website/book where I can find the theory behind this method.

 

Thanks,

 

- Siddharth
