  • Publication number: 20230111901
    Abstract: A method, computer readable medium, and system are disclosed for implementing automatic level-of-detail for physically-based materials. The method includes the steps of identifying a declarative representation of a material to be rendered, creating a reduced complexity declarative representation of the material by applying one or more term rewriting rules to the declarative representation of the material, and returning the reduced complexity declarative representation of the material.

  • Patent number: 10008033
    Abstract: 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.

  • Patent number: 9947132
    Abstract: 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.

  • Patent number: 9501865
    Abstract: A system, method, and computer program product are provided for determining a quantity of light received by an element of a scene. In use, a quantity of light received by a first element of the scene is determined by averaging a quantity of light received by elements of the scene that are associated with a selected set of light paths.
