Abstract
Systems and methods of extracting an isosurface wherein points on the isosurface have a constant value. The method includes dividing a volume into a grid of voxels The method includes identifying intersecting edges in the voxels, wherein the intersecting edges intersect the isosurface. The method includes generating patches for the intersecting edges and tessellating the patches and generating a grid of tessellated vertices. The method includes determining intersection points of the tessellated vertices with the isosurface and moving the intersected vertices to form a finer approximation of the isosurface.
