TriEdgeSetC
Class Description
include	"amma/TriEdgeSet.hh"
User Level:	Default
Library:	tri
Example:	cri.cc
Section:	3D Surface.Polyhedral Representation
In Scope:	std

Comments:
This class allows simple adjacent-triangle finding in TriSetC objects. The class can return an adjacent triangle, given an edge (a pair of vertices) and a current triangle.

TriEdgeSetC(TriSetC & triSet)

Constructor
Creates a TriEdgeSetC corresponding to a TriSetC.

IntT GetAdjacentTriangle(IntT iVertexOne,IntT iVertexTwo,IntT iCurrentTriangle)

Access to adjacent triangle information
Returns the index of the triangle that shares the edge (iVertexOne,iVertexTwo) with iCurrentTriangle

BooleanT AddEdge(IntT iVertexOne,IntT iVertexTwo,IntT iCurrentTriangle)

Adds the edge between iVertexOne and iVertexTwo to the edge list, and associates it with iCurrentTriangle

IntT IndexOf(IntT iLowerVertex,IntT iUpperVertex)

Finds the offset of iUpperVertex in the edge list for iLowerVertex

void OrderVertices(IntT & iVertexOne,IntT & iVertexTwo)

Orders the vertices so that iVertexOne < iVertexTwo
