reflect method

Vector3 reflect(
  1. Vector3 normal
)

Reflect this vector off of plane orthogonal to normal. Normal is assumed to have unit length.

  • normal - the normal to the reflecting plane

Implementation

Vector3 reflect(Vector3 normal) {
  // reflect incident vector off plane orthogonal to normal
  // normal is assumed to have unit length

  return sub(_vector.copy(normal).multiplyScalar(2 * dot(normal)));
}
