byte    setPhysicalSkySunAngles( real zenith, real azimuth );

// It is an alternative way to set the sun position based on spheric angles
// Call this function after setPhysicalSkyGeometry and longitude and latitude parameters will be overriden


byte    setPhysicalSkySunDirection( Cvector dir );

// It is an alternative way to set the sun position based on a direction
// Call this function after setPhysicalSkyGeometry and longitude and latitude parameters will be overriden

byte    setPhysicalSkySun( byte sunActive, real sunTemperature, real sunPowerScaleFactor, real planetReflectance );

// SunActive: 0 or 1, by default sun is enabled (1)
// sunTemperature: in kelvins.
// Default 5777. Range: 100 - 1000000
// sunPowerScaleFactor: total power refered to the Earth's sun.
// For example a value of 0.8 would mean a sun emititng 0.8 times less energy than ours.
// Default: 1.0. Range: Is allowed any value greater than 0.
// planetReflectance: from 0 to 1


byte    setPhysicalSkyAtmosphere( real ozone, real water, real angstromTurbidity, real wavelengthTurbidity, real aerosolAlbedo, real asymmetryFactor );

// ozone: ( cms ) Default: 0.4 Range: Any value greated than 0 (usually between 0 and 1)
// water: water vapor ( cms ) Default: 2.0 Range: Any value greated than 0
// angstrom turbidity: coefficient Default: 0.04 Range: Any value greated than 0
// wavelength turbidity exponent Default: 1.2 Range: Any value greated than 0
// aerosolAlbedo: aerosol albedo Default: 0.8 Range: (0-1)
// asimmetryFactor: "anisotropy" of aerosol. Default: 0.7. Range (-0.99999, 0.99999);

Always check that the RGB colors are in float precision. RGB colors in the 0-255 range should be normalized diving them by 255.0 before passing them to Maxwell
