Abstract
Methods and systems improve quality of a hex-mesh by: performing a first iterative procedure which starts with the input hex-mesh and which outputs an output hex-mesh having improved quality. Performing the first iterative procedure comprises: initializing a current hex-mesh to be equal to the input hex mesh; for each iteration of the first iterative procedure: performing an optimization of an energy function over a plurality of directed-edges in the current hex-mesh to determine updated vertex positions for vertices in the current hex-mesh, wherein for each directed edge, the energy function comprises a term that expresses a preference for the directed edge to be aligned with normal vectors of base triangles of an edge-cone corresponding to the directed edge; and updating the current hex-mesh with the updated vertex positions; and after one or more iterations, setting the output hex-mesh to be equal to the current hex-mesh.
