Method Detail

getMatrix

public abstract AMatrix getMatrix()

getTranslation

public abstract ATranslation getTranslation()

copyOfTranslationVector

public AVector copyOfTranslationVector()

Returns a deep copy of the translation vector for this affine transform

copyOfMatrix

public AMatrix copyOfMatrix()

Returns a deep copy of the transformation matrix for this affine transform

getMatrixTransform

public MatrixTransform getMatrixTransform()

getTranslationVector

public AVector getTranslationVector()

Gets the translation offset that is part of this affine transform.

Returns:

isIdentity

public boolean isIdentity()

Description copied from class: ATransform

Returns true if this transform is known to be the identity function, i.e. it maps all vectors to themselves

Overrides:

isIdentity in class ATransform

compose

public ATransform compose(ATransform a)

Description copied from class: ATransform

Composes this transformation with another transformation, returning a new combined transformation

Overrides:

compose in class ATransform

compose

public ATransform compose(AAffineTransform a)

transform

public void transform(AVector source,
                      AVector dest)

Description copied from interface: ITransform

Transforms the source vector, storing the result in the given destination vector

Specified by:

transform in interface ITransform

Specified by:

transform in class ATransform

transformNormal

public void transformNormal(AVector source,
                            AVector dest)

calculateElement

public double calculateElement(int i,
                               AVector v)

Description copied from class: ATransform

Calculates a single element of the output. Not necessarily faster than calculating full output, but can be in some circumstances.

Overrides:
