ALEXANDRIA, Va., March 19 -- United States Patent no. 12,254,559, issued on March 18, was assigned to AUTODESK INC. (San Francisco).

"Voxel-based approach for design models" was invented by Dale Zhao (New York City, N.Y.), David Benjamin (Brooklyn, N.Y.) and Rui Wang (New York City, N.Y.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A voxel-based design approach enables the creating and modifying of a design model comprising a 3D grid of discrete voxels that is represented by a voxel data structure. The voxel data structure comprises voxel-level entries, each entry corresponding to a voxel based on the 3D location within the 3D grid. The voxel data structure includes a design-level entry for storing design-...
