cross2 method

Vector3 cross2(
  1. Vector3 a,
  2. Vector3 b
)

Cross a with b

Implementation

Vector3 cross2(Vector3 a, Vector3 b ) {
  double ax = a.x, ay = a.y, az = a.z;
  double bx = b.x, by = b.y, bz = b.z;

  x = ay * bz - az * by;
  y = az * bx - ax * bz;
  z = ax * by - ay * bx;

  return this;
