| 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. |
