sortOuterAndHoleLoopsXY MethodStatic

If reverse loops as necessary to make them all have CCW orientation for given outward normal.

  • Return an array of arrays which capture the input pointers.
  • In each first level array:
    • The first loop is an outer loop.
    • all subsequent loops are holes
    • The outer loop is CCW
    • The holes are CW.
  • Call RegionOps.sortOuterAndHoleLoopsXY to have the result returned as a UnionRegion
