Variance Shadow Maps (VSM) is a new arbitrarily filterable soft-shadowing algorithm first introduced at I3D 2006. Flexion Engine, an OpenGL 2.0 API-based 3D graphics engine, offers a VSM demo for omnidirectional light sources using cube maps, namely Omnidirectional Variance Shadow Mapping (OVSM). It also shows Percentage-Closer Filtering (PCF) in order to compare quality and performance against the VSM.
