The Leo demo showcases a real-time DirectX 11 based lighting pipeline that is designed to allow for rendering scenes made of arbitrarily complex materials (including transparencies), multiple lighting models, and minimal restrictions on the number of lights that can be used - all while supporting hardware MSAA and efficient memory usage. Specifically, this demo uses DirectCompute to cull and manage lights in a scene. The end result is a per-pixel or per-tile list of lights that forward-render based shaders use for lighting each pixel. This technique also allows for adding one bounce global illumination effects by spawning virtual point light sources where light strikes a surface. Download"
