Description

We should discuss extending the marching cubes implementation to unstructured meshes. The marching cubes algorithm should work on any quad/hex meshes, even if the connectivity is unstructured. It should work on deformed meshes also, as long as all cells are convex.

@kennyweiss suggested this in the discussion of PR https://github.com/LLNL/axom/pull/1059.

Research direction

Start by reviewing the marching cubes implementation and the discussion in PR 1059. Define how unstructured quad/hex connectivity and deformed convex cells should be supported, including the tests needed to demonstrate correct behavior.
