integratehoseksky

Since	20.0

vector  integratehoseksky(float solar_altitude, float solar_azimuth, float turbidity, vector ground_albedo, int number_of_samples)

Compute the irradiance on a horizontal surface patch from the given Hosek Sky. This is particularly useful for calculating ground colors.

solar_altitude

Altitude of the sun in degrees measured from the horizon.

solar_azimuth

Azimuth angle of the sun in degrees measured from positive X axis.

turbidity

Amount of aerosols in the air. The value range from 1 to 10. Aerosols scatter the lights and decrease the air’s transparency. Higher values create a more desaturated sky with a blurry sun.

ground_albedo

The planet’s reflectance color. This color is used for the Hosek Sky and to calculate the resulting ground color.

number_of_samples

Number of samples to integrate the sky. The default is 32. Use higher values increase accuracy.
