Lighting

To simulate specific lightings we allow the input of C-gamma distributions. This enables the use of non-uniform intensity distributions for any light source. Concerning the spectral information of each light we only use a simple RGB color.

Next images show some rendering results using two different C-gamma distributions for the lighting (up vs. down). We compare the results using a scene with only a plane or with a part too (left vs. right):

Cgamma 1 Cgamma 1 + part
Cgamma 2 Cgamma 2 + part
