ALEXANDRIA, Va., March 26 -- United States Patent no. 12,260,495, issued on March 25.
"Light field volume rendering method" was invented by Matthew Hamilton (St. John's, Canada).
According to the abstract* released by the U.S. Patent & Trademark Office: "A system and method for volume rendering a light field, wherein the light field data is subjected to a layering scheme introducing a partitioning of the hogels into subsets. Each subset corresponding to a sub-volume of the layer volume, corresponds to the sub-region of the layer. Novel partitioning of the data combined with an efficient local memory caching technique, plenoptic downsampling strategies to reduce memory bandwidth requirements and volume rendering algorithm to produce a rend...
