Description:

Instancing is the stagegy of duplicating an object in a scene many times to create the illusion of crowds, grasses, etc. This has the advantage of saving memory, since all polygons are stored once. Each "instance" of the model has a pointer to the BVH for that model. Rather than moving that actual model in the scene, incoming rays are transformed, causing models to appear transformed (moved, sheared, rotated, etc.).
