Method Details

compute

public static SunPosition.Parameters compute()

Starts the computation of SunPosition.

Returns:

SunPosition.Parameters to set.

getAltitude

public double getAltitude()

The visible sun altitude above the horizon, in degrees.

0.0 means the sun's center is at the horizon, 90.0 at the zenith (straight over your head). Atmospheric refraction is taken into account.

See Also:

• getTrueAltitude()

getTrueAltitude

public double getTrueAltitude()

The true sun altitude above the horizon, in degrees.

0.0 means the sun's center is at the horizon, 90.0 at the zenith (straight over your head).

Since:

2.3

• getAltitude()

getAzimuth

public double getAzimuth()

Sun azimuth, in degrees, north-based.

This is the direction along the horizon, measured from north to east. For example, 0.0 means north, 135.0 means southeast, 270.0 means west.

getDistance

public double getDistance()

Sun's distance, in kilometers.

toString

public String toString()

Overrides:
