yac_compute_bnd_triangle()

void yac_compute_bnd_triangle	(	double *	vertices,
		size_t	num_vertices,
		double	triangle[][3],
		size_t	num_tests
	)

computes a spherical triangle that contains all given vertices, the algorithm tries to minimise the size of the triangle

Parameters

[in]	vertices	vertices that are supposed to be within the triangle
[in]	num_vertices	number of vertices in vertices
[out]	triangle	bounding triangle
[in]	num_tests	with increasing number of tests computation time and chance of smaller bounding triangle increases

Remarks

num_tests has to be > 0
