Making my own micro facet BRDF

So im going to do the maths to make the pretty surfaces! So here is a video of a multisampled microfacet fractal render, with shadowing and multisampled shadowing. Im going to convert it to processing a super sum of light-rays, hitting repeitive geometry, in least operations, computing all the light rays simultaneously. That is what cook torrance is, its a bit full on but im going to give it a go! Im hoping to get a shader that can simulate a wet cardboard type effect… it would be good for a game like little big planet!
