colour_hdri.camera_space_to_RGB

colour_hdri.camera_space_to_RGB(RGB: ArrayLike, M_XYZ_to_camera_space: ArrayLike, matrix_RGB_to_XYZ: ArrayLike) → NDArrayFloat

Convert given RGB array from camera space to given RGB colourspace.

Parameters:

• RGB (ArrayLike) – Camera space RGB colourspace array.

• M_XYZ_to_camera_space (ArrayLike) – Matrix converting from CIE XYZ tristimulus values to camera space.

• matrix_RGB_to_XYZ (ArrayLike) – Matrix converting from RGB colourspace to CIE XYZ tristimulus values.

Returns:

RGB colourspace array.

Return type:

numpy.ndarray
