Matrix4x4.MultiplyPoint

説明

この行列で位置を変換します (一般)。

Returns a position v transformed by the current fully arbitrary matrix. If the matrix is a regular 3D transformation matrix, it is much faster to use MultiplyPoint3x4 instead. MultiplyPoint is slower, but can handle projective transformations as well.

  void Start()
  {
    // Find our current location in the camera's projection space.
    Vector3 pt = Camera.main.projectionMatrix.MultiplyPoint(transform.position);
  }
