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

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

reset

public Object reset(Object newState)

Description copied from interface: Resetable

Resets graphics panel to a new state or its initial state.

Specified by:

reset in interface Resetable

Parameters:

newState - new state, if null, use initial state of graphics panel.

Returns:

old state just before setting the new state
