CheL2: The level 2 of CHE

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

• _edgeMap: map that stores a half-edge to represent an edge.
• _tableVertexHalfEdge: Stores the half-edge thar represents each vertex.
• _nEdges: Stores the amount of edges found in the mesh.
• _che: References the Che orchestrator class.

Initializers

• computeEdgeMap()
  • Computes which half-edges represent each edge.
• computeVertexHalfEdge()
  • Computes which half-edge represents each vertex.

Getters

• compoundCount: returns the amount of compounds in the mesh

• getEdgeHalfEdge(heId)

  • returns the edge represented by heId.

• getVertexHalfEdge(vertexId)

  • returns the half-edge that represents the vertex referenced by vertexId.

Relation methods

The methods that find the star of something related to a vertex benefits from the new info in this level.

• relation00(vertexId)

  • Returns the index of the vertices in the star of the vertex identified by vertexId.

• relation02(vertexId)

  • Returns the index of the triangles in the star of the vertex identified by vertexId.

Integrity

• checkEdgeHalfEdge()
  • Checks if all the edges in the _edgeMap are referenced by valid half edges.
• checkValidVertexHalfEdge()
  • Checks if all vertex half edges are valid half-edge values.
• checkVertexfHalfEdgeTable()
  • checks if the amount of elements on the _tableVertexHalfEdge is equal to the amount of vertices in the mesh
