SectorOffsetProperties Class

Sector properties during offset.

  • this.normal may be initially assigned as the facet normal but can mutate by averaging with neighbors.
  • this.xyz is initially the base mesh xyz but is expected to move along the normal.
  • this.count is used locally in computations.
