compute_angle() static double compute_angle ( POINT4D  p, POINT4D  vs, POINT4D  ve  ) inlinestatic Computes the signed length of the cross product of the vectors (vs, p) and (vs, ve) The sign of this value determines the relative position between p and the line l going though segment (vs, ve) (oriented towards ve) angle > 0: p is on the right of l angle = 0: p is on l angle < 0: P is on the left of l
