Ray Tracing is a global illumination based rendering method. It traces rays of light from the eye back through the image plane into the scene. Then the rays are tested against all objects in the scene to determine if they intersect any objects. If the ray misses all objects, then that pixel is shaded the background color. phifer bronze screenWebThis paper aims to survey several aspects behind the use of grids in ray tracing, in particular grid traversal algorithms, building techniques and several approaches for hierarchical grids.
