colour.RGB_colourspace_pointer_gamut_coverage_MonteCarlo(colourspace: colour.models.rgb.rgb_colourspace.RGB_Colourspace, samples: int = 1000000, random_generator: Callable = random_triplet_generator, random_state: numpy.random.mtrand.RandomState | None = None) → float[source]#

Return given RGB colourspace percentage coverage of Pointer’s Gamut volume using Monte Carlo method.

Parameters

colourspace (colour.models.rgb.rgb_colourspace.RGB_Colourspace) – RGB colourspace to compute the Pointer’s Gamut coverage percentage.
samples (int) – Samples count.
random_generator (Callable) – Random triplet generator providing the random samples.
random_state (numpy.random.mtrand.RandomState | None) – Mersenne Twister pseudo-random number generator to use in the random number generator.

Returns

Percentage coverage of Pointer’s Gamut volume.

Return type

float
