  • Adaptive Pixel Sampling Order for Temporally Dense Rendering
    Publication number: 20230269391
    Abstract: A method dynamically selects one of a first sampling order and a second sampling order for a ray trace of pixels in a tile where the selection is based on a motion vector for the tile. The sampling order may be a bowtie pattern or an hourglass pattern.
    Type: Application

  • Adaptive sampling at a target sampling rate
    Patent number: 11282258
    Abstract: Image quality can be improved by rendering the image based on an importance map that indicates regions of the image that will benefit from more samples. Adaptive sampling determines a number of samples for each pixel of the image using a target sampling rate and the importance map for the image. The number of samples for each pixel needs to be a non-negative integer value, so the per-pixel sampling rates are quantized using per-pixel random values. The resulting quantized sampling rates provides a distribution of samples that closely matches the importance map. The per-pixel random values may vary over time so that the average of the distribution more closely matches the importance map.

  • Reconstruction for temporally dense ray trace rendering
    Patent number: 11120609
    Abstract: A method dynamically selects one of a first sampling order and a second sampling order for a ray trace of pixels in a tile where the selection is based on a motion vector for the tile. The sampling order may be a bowtie pattern or an hourglass pattern. Subframes generated based on the sampling order are communicated over a bus along with motion vectors for tiles of the subframes.
