#define BG_3D_BALLPIVOT_DEFAULT_RADIUS   -1

Surface Reconstruction using Ball Pivoting.

This functionality is based on the Bernardini et. al. work from 1999 describing a method of defining a surface on a point cloud with normals by "rolling" a 3D ball over the set of points and creating triangles where the ball does not fall through.

Build a surface reconstruction (triangle mesh) using the Ball Pivot methodology. Note that this has fewer topology guarantees as compared to the SPSR method, so callers must validate that the output has the properties they are looking for.

Parameters

[out]	faces	set of faces in the output surface, stored as integer indices to the vertices. The first three indices are the vertices of the face, the second three define the second face, and so forth.
[out]	num_faces	the number of faces in the faces array
[out]	vertices	the set of vertices used by the surface.
[out]	num_vertices	the number of vertices in the surface.
	input_points_3d	The input points
	num_input_pnts	the number of points in the input set
	radii	array of ball radii to be used. If NULL, a default radius set is calculated based on the point data.
	radii_cnt	number of radii in radii array

Returns

0 if successful, else error
