This class represents the level 2 of CHE, it stores the a direct reference of each element of a mesh, i.e. sets a half-edge to represent each vertex, and a half-edge to represent each edge.

Attributes

• _nCurves: stores the amount of boundary curves of the mesh.
• _tableCurveHalfEdge: Stores the half-edge that represents each curve.
• _che: References the Che orchestrator class.

Initializers

• computeCurveHalfEdge()
  • Computes which half-edges represent each curve.

Getters

• getCurveHalfEdge(curveId)
  • returns the half-edge that represents a boundary curve.

Setters:

• setSpecialOpposite(heId, nCurve)
  • sets the opposite of a half-edge that does not contain an opposite, to the Boundary Curve it is a part of.

Integrity

• checkTableCurveHalfEdge()

• Checks if the value stored in _nCurves is the number of elements in the _tableCurveHalfEdge array.

• checkOpposites()

• checks if all the values in the level 1 table of opposites reference an valid half edge or an existing boundary curve.
