WebThere are three main procedures: skipping ahead to a given point, advancing the state, and generating points from the state. We will examine how to parallelize the latter two procedures first, and then return to the question of skipping ahead. View chapter Purchase book Generating random numbers Manfred Gilli, ... WebThese rays are called primary rays (or camera or eye rays) because they are the first rays cast into the scene (secondary rays are used to compute things like shadows, reflections, refractions, etc.). To find if the ray intersects a surface, we need to test each object in the scene for a possible intersection against this ray.
