Method Detail

getName

public java.lang.String getName()

Description copied from interface: Component

Get the name of this component.

getDescription

public java.lang.String getDescription()

Description copied from interface: Component

Get the description of this component.

isInverse

public boolean isInverse(Transformer obj)

Description copied from class: Transformer

Are these two transformations, inverses of each other? This method is used to optimize a series of transformations where transformations.

Specified by:

isInverse in class Transformer

inverse

public Transformer inverse()

Description copied from class: Transformer

Get the inverse of the transformation. If the order matters, then the inverse is to be applied after the original transformation. This is primarily an issue with Converters.

Specified by:

inverse in class Transformer

transform

public void transform(double[] plane,
                      double[] sphere)

Description copied from class: Transformer

Convert a single point where the output vector is supplied.

Specified by:

transform in class Transformer

Parameters:

plane - The input vector.

sphere - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.

deproject

public double[] deproject(double x,
                          double y)

Deproject from the plane to the sky. Note that deproject uses the [-1,1] range of plane coordinates while transform uses [-pi/2,pi/2].
