distanceBetweenFaces()

double distanceBetweenFaces	(	const std::pair< unsigned int, vec3 > &	face1,
		const std::pair< unsigned int, vec3 > &	face2,
		std::vector< vec3 > *	path = nullptr )

Returns the geodesic distance between the points of two faces, -1 if indices are invalid.

First element of the pair spesifies the id of the face, the second element specifies a point that is located within the face

distance()

std::vector< double > distance	(	const std::vector< unsigned int > &	VS,
		const std::vector< unsigned int > &	FS,
		const std::vector< unsigned int > &	VT,
		const std::vector< unsigned int > &	FT,
		std::vector< std::vector< vec3 > > *	contours = nullptr )

Exact geodesic distance.

Parameters

VS	vector specifying indices of source vertices
FS	vector specifying indices of source faces
VT	vector specifying indices of target vertices
FT	vector specifying indices of target faces
contours	optional output vector cntaining the shortest paths to targets

Returns

#VT+#FT vector of geodesic distances of each target w.r.t. the nearest one in the source set

Note

Specifying a face as target/source means its center
