A method, system, and computer program product for performing a lighting simulation are disclosed. The method includes the steps of receiving a three-dimensional (3D) model, receiving a set of probes, where each probe specifies a location within the 3D model and an orientation of the probe, and performing, via a processor, a lighting simulation based on the 3D model, the set of probes, and one or more light path expressions. The light path expressions are regular expressions that represent a series of events, each event representing an interaction of a ray at a location in the 3D model.

A system and method for propagating scene information to a renderer. In one embodiment, the system includes: (1) an update request receiver operable to receive an update request from the renderer and determine a point from which the renderer is to be updated and (2) an update propagator associated with the update request receiver and operable to employ a graph containing scene information to construct a change list corresponding to the update request and transmit the change list toward the renderer.
