Magic Sprites - Sprite based refraction and other Sprite Effects

Modern 3d graphics hardware provides a host of capabilities for fast 2d sprite effects. This papers describes an implementation of several fragment shaders that give realistic details to simple sprites. In particular bump mapping, relief mapping, and sprite based refraction have been implemented. Performance and possible future direction is also discussed.
