Indicator interface that identifies a triangle fan.
A TriangleFan is a type of surface patch used to construct a MultiPatch, defined by a collection of Points that specify the triangle surfaces that comprise it. The first point in the TriangleFan is the origin point and is included in all of the triangle surfaces. For a TriangleFan with six points, the triangle surfaces are defined by points: (0, 1, 2), (0, 2, 3), (0, 3, 4), (0, 4, 5). The front side is established by orienting the first three vertices clockwise.
