Sample given light probe to find lights using Viriyothai (2009) variance minimization light probe sampling algorithm.

Parameters

  • light_probe (array_like) – Array to sample for lights.

  • lights_count (int) – Amount of lights to generate.

  • colourspace (colour.RGB_Colourspace, optional) – RGB colourspace used for internal Luminance computation.

Returns

list of colour_hdri.sampling.variance_minimization.Light_Specification lights.

Return type

list
