Public NotInheritable Class Mesh

The Mesh type exposes the following members.

Constructors

	Name	Description
	Mesh	Creates a new empty mesh instance.
	Mesh(ArrayList, ArrayList, ArrayList)	Creates a new mesh instance with the given points, triangles and lines. Does not check the indices in the given triangles and lines array lists for correctness.

Properties

	Name	Description
	Lines	An array list of indices (as integers) pointing to the points array list. Two consecutive indices always represent a single line.
	Points	An array list of point objects representing the mesh points.
	Triangles	An array list of indices (as integers) pointing to the points array list. Three consecutive indices always represent a single triangle.

Methods

	Name	Description
	AddLine	Adds a new line in the mesh.
	AddPoint	Adds a new point in the mesh.
	AddTriangle	Adds a new triangle in the mesh.
