I’m currently doing some experiments with Spherical Harmonics lighting, with all sample coefficients calculated (or rather: pre-calculated, as it – sadly! – turns out) on the GPU. I’ll be posting some screenshots in the next couple of days till I get fed-up with the technique and decide to move on 🙂
The screen-shots will be posted without any post-processing applied, so please forgive me for lack of any proper anti-aliasing / color grading / tone mapping / what-not. You have been warned.
(..and if you ask, yes: I’m aware of various artifacts in the shots.. 🙂 )
