Abstract
A system, method, and computer program product are provided for efficiently ray tracing micropolygon or other highly complex geometry. In operation, a first hierarchy of a plurality of objects is established. Additionally, rays are traced using the first hierarchy to efficiently identify which of the plurality of objects are potentially intersected. Furthermore, at least one of the potentially intersected objects are decomposed, on-demand, into a set of subobjects, each set of subobjects corresponding to one of the at least one of the potentially intersected objects. Still yet, a second hierarchy is established for at least one of the set of subobjects, the second hierarchy being determined by a connectivity of subobjects in an associated set of subobjects in order to accelerate ray tracing.
