BasicRemeshPass()

Linear edge-refinement pass, followed by smoothing and projection

  • Edges are processed in prime-modulo-order to break symmetry
  • smoothing is done in parallel if EnableParallelSmooth = true
  • Projection pass if ProjectionMode == AfterRefinement
  • number of modified edges returned in ModifiedEdgesLastPass

Precompute()

we can vastly speed things up if we precompute some invariants. You need to re-run this if you are changing the mesh externally between remesh passes, otherwise you will get weird results. But you will probably still come out ahead, computation-time-wise
