Ray-Traced Approximate Reflections Using a Grid of Oriented Splats

Until now, real-time reflections have been realized by one or a combination of the following techniques:

1. Flat Reflectors. Mirror the camera to render a reflection texture.

2. Reflections through a set of environment maps. An approximation of the real reflections seen at a specific surface point in the scene is generated. Usually environment maps are used to realize reflections of distant objects.
