Latest Patents
Wyman's latest patents include "Illumination resampling using temporal gradients in light transport simulation systems and applications." This patent describes systems and methods that relate to the generation of image content. The approach aims to provide smoothing between sequential images while avoiding lag in lighting effects. By comparing light information for regions between consecutive rendered frames, shading can be performed, and results can be compared for tiles of pixels to compute gradient values. A filtering pass can be executed with respect to these gradients, allowing for the upscaling of a lower-resolution grid version into a full-resolution image. The gradients are transformed into confidence values, which help determine the extent to which lighting data from the previous frame should be retained.
Another patent, "Initial candidates in spatiotemporal resampling," presents approaches for selecting and reusing lighting sample data. This method generates high-quality initial candidates that are more representative of the actual lighting of a scene. Instead of discarding important light samples, some can be provided as additional, unweighted candidates for use in importance sampling. This ensures that significant lights are considered when shading pixels for a scene, especially when changes occur in the scene or location.
