A dynamic volumetric medium, such as hair, fog, or smoke, may be represented, for purposes of shadow mapping, by transmittance versus depth data for that medium. In one embodiment, the representation may take the form of a plot of transmittance versus depth, with nodes where the transmittance changes non-live linearly with respect of depth into the medium. The number of nodes in the representation may be reduced to reduce memory footprint and to enable the storage of the representation on the same chip doing the shadow mapping. In some embodiments, the number of nodes may be reduced, one node at a time, by removing the node whose underlying trapezoid has the least area of all the remaining nodes.

Shadowing dynamic volumetric media

A method, apparatus, and system are described for list texturing being performed over a data path of a graphics pipeline. Input data is received at a graphics pipeline of a graphics processing unit to be processed and generated into a final image to be displayed on a display device of a computer system. Geographic primitives are obtained from processing the input data, and neighbor aggregation of pixels within the geographic primitives is performed. The neighbor aggregation of the pixels includes rendering list texture of the pixels by merging the geographic primitives.

An interactive cinematic lighting system used in the production of computer-animated feature films containing environments of very high complexity, in which surface and light appearances are described using procedural RenderMan shaders. The system provides lighting artists with high-quality previews at interactive framerates with only small approximations compared to the final rendered images. This is accomplished by combining numerical estimation of surface response, image-space caching, deferred shading, and the computational power of modern graphics hardware.

Computer operations are partitioned for execution by a processor. A plurality of operations to be partitioned is received. The respective priorities for each of the plurality of operations is determined. Ready operations are identified, where a ready operation is an operation that does not have any predecessor operations that have not yet been added to a partition. A determination is made whether adding the ready operations with the highest priorities to the current partition would violate a hardware resource constraint. Based on this determination, the ready operations are added to the partition. The operations added to the partition are provided to a processor for execution.
