Does anyone have a link to a sample implementation of how to create/handle 4D BRDFs?

I found a few interesting papers and websites,

but cannot seem to find any reference implementation to play with. Anyone have any?

This question is unclear to me. There are quite a lot of different BRDF models out there; which one(s) do you want a reference implementation for? – Nathan Reed Oct 17 '11 at 23:43
Any one, to give me an idea of how they are programmed! – bobobobo Oct 18 '11 at 1:54

nVidia's own site has an entry on SBRDF if you want source for a spatial variant on pure BRDF. Check here: brdflab.sourceforge.net for an open source (Ogre3D based) application. – Patrick Hughes Oct 18 '11 at 4:49
@PatrickHughes Great! – bobobobo Oct 19 '11 at 21:17

There are quite a few implementations of BRDFs in pbrt, the (open-source) raytracer described by the Physically Based Rendering book. That book is also a great reference for anyone interested in 3D graphics, even if you're not interested in raytracing.

I am interested! Very interested. – bobobobo Oct 19 '11 at 21:15
