Constructor Detail

NullProjection

public NullProjection()

Creates a null projection.

Method Detail

getFormula

public String getFormula()

Description copied from interface: Projection

Returns the formula in text readable form

Specified by:

getFormula in interface Projection

Overrides:

getFormula in class AbstractProjection

transform

public double[] transform(double[] xyz)

Description copied from interface: Projection

Returns an array of length 3: uvw = projection(xyz). The returned array may have a lifetime up to the next call to this method on this object.

Specified by:

transform in interface Projection

Specified by:

transform in class AbstractProjection

transform

public double[][] transform(double[][] xyz,
                   int n)

Description copied from class: AbstractProjection

Implements this method in terms of double[] transform(double[] xyz). Not a very efficient implementation, so concrete projections should probably override this method with something better.

Specified by:

transform in interface Projection

Overrides:

transform in class AbstractProjection

deltaTransform

public double[] deltaTransform(double[] xyz)

Description copied from interface: Projection

Returns an array of length 3: uvw = delta projection(xyz). The returned array may have a lifetime up to the next call to this method on this object.

Specified by:

deltaTransform in interface Projection

Specified by:

deltaTransform in class AbstractProjection

inverseTransform

public double[] inverseTransform(double[] uvw)
                          throws UnsupportedOperationException

Description copied from interface: InverseProjection

Returns an array of length 3: xyz = inverse projection(uvw). The returned array may have a lifetime up to the next call to this method on this object. UnsupportedOperation is thrown in no inverse projection is possible.

Specified by:

inverseTransform in interface InverseProjection

Throws:

UnsupportedOperationException

inverseDeltaTransform

public double[] inverseDeltaTransform(double[] uvw)
                               throws UnsupportedOperationException

Description copied from interface: InverseProjection

Returns an array of length 3: xyz = inverse delta projection(uvw). The returned array may have a lifetime up to the next call to this method on this object. UnsupportedOperation is thrown in no inverse delta projection is possible.

Specified by:

inverseDeltaTransform in interface InverseProjection

Throws:

UnsupportedOperationException

copy

public Projection copy()

Description copied from interface: Projection

Returns a deep copy of the projection.

Specified by:

copy in interface Projection

Specified by:

copy in class AbstractProjection
