dist3d_pt_seg() static double dist3d_pt_seg ( POINT3DZ *  p, POINT3DZ *  A, POINT3DZ *  B  ) static Return the 3D distance between the point the segment. Parameters [in] p Point [in] A,B Points defining the segment Note Derived from the PostGIS function lw_dist3d_pt_seg in file measures3d.c See also http://geomalgorithms.com/a02-_lines.html
