# Triangle

A single triangle within a Mesh.

Note: d3 triangle edges are indexed clock-wise from each vertex; This means:  
Vertex | ‘to the right of’ | opposite |  
v0 | e0 | e1 |  
v1 | e1 | e2 |  
v2 | e2 | e0 |  
Neighbouring triangles share edges, and their corresponding edge’s index (in  
the other triangle) can be queried via iNeighbourEdge().  
If a Mesh is not closed, then triangles on the boundary will have less than  
3 neighbouring triangles.
