This allows adding a "fake" sun beam effect, simulating crepuscular rays from light being scattered in a medium like the atmosphere or deep water. Such effects can be created also by renderers using volumetric lighting, but the compositor feature is a lot cheaper and is independent from 3D rendering. This makes it ideally suited for motion graphics. The implementation uses am optimized accumulation method for gathering color values along a line segment. The inner buffer loop uses fixed offset increments to avoid unnecessary multiplications and avoids variables by using compile-time specialization (see inline comments for further details). |
