Re: [GSoC 2013] Advanced Rendering Techniques - Skin/Hair

Hi Girish,

Although we have a Marschner shader model, we had some issue with it so we
defaulted to using Kajiya and Kay shading model which gives decent results
and is much faster. You can find more about what is implemented here:
http://hairrendering.wordpress.com
We also have a SSS shader implementation used for skin based on
http://www.gamedev.net/topic/481494-sub-surface-scattering-hack--comments-wanted-/

I haven't worked on CS in a while now, so I am not sure what the priorities
of improving these rendering techniques are for the project.

Cheers,
Alex.
