ComputePolygonPlane()

template<typename RealType >

void GEOMETRYCORE_API PolygonTriangulation::ComputePolygonPlane	(	const TArray< TVector< RealType > > &	VertexPositions,
		TVector< RealType > &	PlaneNormalOut,
		TVector< RealType > &	PlanePointOut
	)

ComputePolygonPlane< double >()

TriangulateSimplePolygon() [1/2]

template<typename RealType >

void GEOMETRYCORE_API PolygonTriangulation::TriangulateSimplePolygon	(	const TArray< TVector2< RealType > > &	VertexPositions,
		TArray< FIndex3i > &	OutTriangles,
		bool	bOrientAsHoleFill = true
	)

Compute triangulation of simple 2D polygon using ear-clipping

Parameters

VertexPositions	ordered vertices of 2D polygon
OutTriangles	computed triangulation. Each triangle is a tuple of indices into VertexPositions.
bOrientAsHoleFill	if true, output triangles are wound opposite of the input polygon; this is typically desired when the polygon comes from the boundary of a hole

	)

Compute triangulation of 3D simple polygon using ear-clipping

Parameters

OutTriangles	computed triangulation. Each triangle is a tuple of indices into VertexPositions.
bOrientAsHoleFill	if true, output triangles are wound opposite of the input polygon; this is typically desired when the polygon comes from the boundary of a hole
