yac_generate_cubed_sphere_grid_information()

void yac_generate_cubed_sphere_grid_information	(	unsigned	n,
		unsigned *	num_cells,
		unsigned *	num_vertices,
		double **	x_vertices,
		double **	y_vertices,
		double **	z_vertices,
		unsigned **	vertices_of_cell,
		unsigned **	face_id )

Creates a cubed sphere grid with n subdivisions

This routine is based on Matlab code provided by Mike Hobson and written by Mike Rezny (both from MetOffice)

Parameters

[in]	n	number of subdivisions of the cubed sphere grid
[out]	num_cells	number of cells in the grid
[out]	num_vertices	number of vertices in the grid
[out]	x_vertices	x coordinate of vertices
[out]	y_vertices	y coordinate of vertices
[out]	z_vertices	z coordinate of vertices
[out]	vertices_of_cell	vertex indices for each cell
[out]	face_id	id for orientation of face w.r.t cube faces (unused)

Remarks

Vertex coordinates are provided in Cartesian coordinates on a unit sphere, with the center of the sphere being the origin of the coordinate system.
