WebWhenever a ray hits a surface, a new ray is traced from that hitpoint in a random direction until the maximum path depth is reached or until a Russian roulette-like mechanism kills the ray. As a result, Brigade is able to produce effects like diffuse color bleeding, glossy (blurry) reflections, soft shadows, real area lights, true depth of field, and much more.
