Matching Constraints

• Validity of match

  • A scene node can map to only one model node, and a model node cannot be mapped by more than one scene node

• Similarity of primitives

  • Same sign, same type, similar size

• Preservation of precedence graph

  • Primitives should have the same precedence
  • Gluing arcs should correspond

• Preservation of geometry

  • Minimize distances between reference points and angles between reference vectors of primitives
