Abstract: We present a new method for extracting crack-free isosurfaces from adaptive mesh refinement (AMR) data. This method builds on prior work, which utilizes dual grids and stitch cells that fill the resulting gaps. To simplify implementation of stitch cell generation, we propose a case-table-based approach. The most significant benefit of our new technique is that it uses ghost data to handle parallel isosurface extraction in a distributed memory environment efficiently.
