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

Hi Christian and Alex,

I am going through the code to see whether I can figure out the issue and
confirm wether it is as you said, as it definitely could be it. Alex, do
you plan to check and work on the error? If not, I will try to work on
fixing the issue or else reimplementing it might be a better idea, if it is
not this issue, as Alex said. The task of updating the physical animation
controller should be a simple one and I will add it to my proposal
nonetheless. Well, I do think this one would be OK regarding the SSS
technique, although I will research more on the SSS technique for the skin
shader and see whether there is a simpler implementation, but I think this
should definitely be doable even with the complexity of the diffusion maps.
Now the question is whether I should tackle both tasks of skin and hair
rendering because I am not sure whether it will be possible to work on both
and finish both within 3 months! Do let me know what you think.Thanks!

Regards,
Girish
