Vector3 transform(
  1. Vector3 arg
)

Transform arg of type Vector3 using the transformation defined by this.

Implementation

Vector3 transform(Vector3 arg) {
  final argStorage = arg._v3storage;
  final x_ = (_m3storage[0] * argStorage[0]) +
      (_m3storage[3] * argStorage[1]) +
      (_m3storage[6] * argStorage[2]);
  final y_ = (_m3storage[1] * argStorage[0]) +
      (_m3storage[4] * argStorage[1]) +
      (_m3storage[7] * argStorage[2]);
  final z_ = (_m3storage[2] * argStorage[0]) +
      (_m3storage[5] * argStorage[1]) +
      (_m3storage[8] * argStorage[2]);
  arg
    ..x = x_
    ..y = y_
    ..z = z_;
  return arg;
