Problem

The isosurface extraction relies on the marching cube algorithm, which generates artifacts at the boundary between grid of different densities (as highlighted in the doc).

Potential improvements

There are some papers out there with possible solution to generate crack-free isosurfaces on non-uniform grids.
Here are a few resources that could be explored:

  1. Visualization of AMR Data With Multi-Level Dual-Mesh Interpolation
  2. Dual Marching Cubes: Primal Contouring of Dual Grids
