Efficient ray tracing without acceleration data structure

摘要

Methods, systems and computer program code (software) products executable in a digital processor operable to simulate light transport in a scene by ray tracing (wherein the digital processor is operable to maintain an object list representing a list of objects associated with a boundary of the scene) include executing a ray tracing method that traces r rays through n objects by (1) partitioning the object list in a recursive manner to generate partitions and (2) culling away the partitions of objects from rays, without using an explicit auxiliary acceleration data structure.
