Module Contents

.. py:class:: UniformKind

   Bases: :py:obj:`enum.Enum`


   Generic enumeration.

   Derive from this class to define new enumerations.


   .. py:attribute:: INT
      :value: 'int'



   .. py:attribute:: FLOAT
      :value: 'float'



   .. py:attribute:: BOOL
      :value: 'bool'



   .. py:attribute:: VEC2
      :value: 'vec2'



   .. py:attribute:: VEC3
      :value: 'vec3'



   .. py:attribute:: VEC4
      :value: 'vec4'



   .. py:attribute:: MAT3
      :value: 'mat3'



   .. py:attribute:: MAT4
      :value: 'mat4'



.. py:class:: ShaderUniform

   .. py:attribute:: name
      :type:  str


   .. py:attribute:: location
      :type:  int


   .. py:attribute:: value
      :type:  Union[int, float, Sequence[float], numpy.ndarray, bool, None]
      :value: None



   .. py:attribute:: uniform_type
      :type:  Optional[UniformKind]
      :value: None



   .. py:method:: __post_init__()


   .. py:method:: infer_type(v: Any) -> UniformKind
      :staticmethod:



   .. py:method:: upload(gl_module=None) -> None

      Upload the current value to the bound GL program using PyOpenGL-like calls.
      If location < 0 (GL returns -1 when not found/used), this is a no-op.

      - gl_module: optional OpenGL.GL-like module. If None, will try to import PyOpenGL
        (from OpenGL import GL as GL) at call time.



   .. py:method:: __str__() -> str
