The introduced method and system use a 4-dimensional (4D) light field as a background of a scene, instead of 2D background image. Realizing computing a light field takes tremendous amounts of processing power, data storage and time (even with the currently available hardware), the introduced method and system compute and store the light field before rendering a scene. To reduce the time storing and accessing the light field during the rendering process, the introduced method and system also uses a modified video codec to compress and decompress the light field as 2D images.

Light fields as better backgrounds in rendering

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.

Lighting simulation analysis using light path expressions

A material representation data structure and a method of representing a material for digital image synthesis. The data structure may be embodied in a graphics processing subsystem, including: (1) a memory configured to store a material representation data structure according to which a material is declaratively represented by a property indicative of an interaction between the material and light, and (2) a processor operable to gain access to the memory and employ the property in a rendering procedure defined independent of the material representation data structure and designed to effect the interaction.
