angle2C static method

double angle2C(
  1. Coordinate p0,
  2. Coordinate p1
)

Returns the angle of the vector from p0 to p1, relative to the positive X-axis. The angle is normalized to be in the range -Pi, Pi .

@param p0 the initial point of the vector @param p1 the terminal point of the vector @return the normalized angle (in radians) that p0-p1 makes with the positive x-axis.

Implementation

static double angle2C(Coordinate p0, Coordinate p1) {
  double dx = p1.x - p0.x;
  double dy = p1.y - p0.y;
  return math.atan2(dy, dx);
}
