Indicator interface that identifies a Triangles patch.
A Triangles part 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. Each consecutive triplet of vertices defines a new triangle, and the vertex count must be a multiple of three. For a Triangles part with six points, the triangle surfaces are defined by points: (0, 1, 2), (3, 4, 5). The front side of each triangle is established by orienting its vertices clockwise.
