Cycles: add back light intersection for multiple importance sampling * Intersect closest kernel now intersects with point, spot and area lights in addition to scene geometry. This could later be optimized by adding lights to the BVH. * If such a light is hit, the new shade_light kernel will be executed which will evaluate the light shader and write to the render buffer, then continue with intersect_closest. * The shade_background kernel handles intersection and shader evaluation for distant lights. |
