Method Detail

getMatrixComponent

public abstract AMatrix getMatrixComponent()

getTranslationComponent

public abstract ATranslation getTranslationComponent()

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

isIdentity

public boolean isIdentity()

Description copied from class: ATransform

Returns true if this transform is 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 class: ATransform

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

Specified by:

transform in class ATransform

calculateComponent

public double calculateComponent(int i,
                        AVector v)

Description copied from class: ATransform

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

Overrides:

calculateComponent in class ATransform

transformInPlace

public void transformInPlace(AVector v)

Description copied from class: ATransform

Transforms a vector destructively. Intended for fast non-allocating transforms

Overrides:

transformInPlace in class ATransform

toAffineTransform

public AAffineTransform toAffineTransform()

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

equals

public boolean equals(AAffineTransform a)

inverse

public AAffineTransform inverse()

Description copied from class: ATransform

Return the inverse of this transformation if possible

Overrides:

inverse in class ATransform

Returns:
