.. py:function:: perspective(fovy: float, aspect: float, znear: float, zfar: float) -> numpy.ndarray

   Create a perspective projection matrix.

   :param fovy: Field of view angle in the y-direction, in degrees.
   :type fovy: float
   :param aspect: Aspect ratio of the viewport (width / height).
   :type aspect: float
   :param znear: Distance to the near clipping plane (must be > 0).
   :type znear: float
   :param zfar: Distance to the far clipping plane (must be > znear).
   :type zfar: float

   :return: A 4x4 perspective projection matrix.
   :rtype: numpy.ndarray
