Fast Shadow Receiver

Shadows are very important aspects in 3D space. However, shadow rendering is GPU intensive process. Fast Shadow Receiver makes shadow rendering much faster by minimizing the area where shadows are drawn.
This is the real solution to the shadow performance problem on low-end mobile devices.

Also, Fast Shadow Receiver provides a useful mesh search tree called “Mesh Tree” which is used to search for polygons which are receiving shadows. Mesh Tree is useful not only for shadows but also for various purpose such as light projection, bullet marks, AI, and so on.
