public class MappedPolygon2D
extends java.lang.Object
implements java.lang.Cloneable
Implements a node mapping between two Polygon2D shapes. Mapping uses radial representation to assign similarity weights to node pairs, and maps between nodes based upon these weights. This allows mappings between polygons with unequal node counts. The algorithm:
  • Gets the radial representation of each polygon
  • Assigns weights to node pairs based upon angle similarity
  • First maps nMin nodes, where nMin = min(nA, nB), ensuring that each node gets mapped at least once
  • Secondly maps remaining unmapped nodes based upon their weights and positions relative to already mapped nodes (ensuring that node order is preserved)

    • removeNodeByCount

      public int removeNodeByCount​(double minAngle, double minLength)
      Remove a node from A, selected by the criteria that its target has a maximum source count (i.e., multiple source (A) nodes mapped to a single target (B) node), and is attached to a minimal length edge.
      Parameters:
      minAngle - the minimum node angle at which a node remove a node is allowed (may no longer be necessary...)
