ARF Shadow Explorer was designed for shadow map technique comparison. Currently it has four techniques implemented:simple shadow maps, percentage closer shadow maps, variance shadow maps and exponential variance shadow maps. Two different scenes and a full set of parameters should keep us busy for a while 🙂
Graphics Runner blog. Instant Radiosity is a theoretically simple method. It traces paths from the primary light source and creates virtual point lights (VPL) when the path hits the scene. These VPLs approximate the reflected light from that region of the scene. The path can then be reflected, possibly with a new random direction, and … Read more
