According to the abstract* released by the U.S. Patent & Trademark Office: "A method and system provide for extracting an isosurface. A set of three-dimensional (3D) asymmetric sampling grids are created based on a sampling resolution and a region of interest. The set of grids cover a 3D scalar field and are tiles made up of tetrahedrons. The 3D scalar field is evaluated based on the set of 3D asymmetric sampling grids to generate a value for each tile, convert the values to cells, and assign an index to each cell. For each cell, the ...
