Description

Triangulates a polygon, with an optional hole, on a central body, into a triangle mesh and a surrounding boundary. The mesh is commonly visualized with the Triangle Mesh Primitive or Surface Mesh Primitive. The boundary is commonly visualized with the Polyline Primitive.

Compute	Computes the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified positions. This is equivalent to calling Compute with an `altitude` of `0`, a `granularity` of `1` degree, and a `positionsWindingOrder` of Compute.
ComputeCartographic	For convenience. Computes the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified Cartographic positions. Longitude and latitude are in radians, and altitude is in meters. This is equivalent to converting each position in positions to Cartesian and calling Compute
ComputeCartographicWithAltitudeAndGranularity	For convenience. Computes the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified Cartographic positions. Longitude and latitude are in radians, and altitude is in meters. This is equivalent to converting each position in positions to Cartesian and calling Compute
ComputeWithAltitudeAndGranularity	Computes the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified positions.
ComputeWithHole	Computes the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified positions with a hole specified by holePositions. This is equivalent to calling Compute with an `altitude` of `0` and a `granularity` of `1` degree.
ComputeWithHoleAltitudeAndGranularity	Computes the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified positions with a hole specified by holePositions.
