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

Parameters:

• light_probe (_SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | bool | int | float | complex | str | bytes | _NestedSequence[bool | int | float | complex | str | bytes]) – Array to sample for lights.

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

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

Returns:

list of colour_hdri.sampling.variance_minimization.Light_Specification lights.

Return type:

list
