Indicator interface that identifies a triangle fan.
A TriangleFan is a type of surface patch used to construct a MultiPatch. A TriangleFan is defined by a Collection of Points that define the triangle surfaces in the TriangleFan. The first point in the TriangleFan is the origin point of the fan and is included in all of the triangle surfaces. For a TriangleFan with Points 0 to N, the triangle surfaces are defined by Point 0, Point i, and Point i+1 (for i = 1 to N-1).
