Constructor Detail

EgocentricDirection

public EgocentricDirection(SmallAngle az,
                   SmallAngle el)

Method Detail

makeFromRad

public static EgocentricDirection makeFromRad(double azRad,
                              double elRad)

makeFromDeg

public static EgocentricDirection makeFromDeg(double azDeg,
                              double elDeg)

getForwardDirection

public static EgocentricDirection getForwardDirection()

getAzimuth

public SmallAngle getAzimuth()

getElevation

public SmallAngle getElevation()

add

public EgocentricDirection add(EgocentricDirection other)

subtract

public EgocentricDirection subtract(EgocentricDirection other)

Returns:

EgocentricDirection-delta, which should be distinguished by type.

computeDistanceAngle

public SmallAngle computeDistanceAngle(EgocentricDirection other)

Returns:

"distance angle" estimate, computed as a magnitude of the vector of component angle distances, which is probably not exactly the spherical angle we want, but it's close enough for the observation-cognitive-distance algorithm, which is the only place it's used at present. TODO: compute the real spherical angle using an inverse cosecant or whatever.

toString

public String toString()

Overrides:
