ATranslation

public ATranslation()

Method Detail

getTranslationVector

public abstract AVector getTranslationVector()

Gets the vector offset that this translation represents. Not guaranteed to be a reference.

Returns:

dimensions

public int dimensions()

Returns the number of dimensions of this translation

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:

calculateElement in class AAffineTransform

getTranslationComponent

public double getTranslationComponent(int i)

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 interface ITransform

Overrides:

transform in class AAffineTransform

transformNormal

public void transformNormal(AVector source,
                   AVector dest)

Overrides:

transformNormal in class AAffineTransform

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 AAffineTransform

toAffineTransform

public AAffineTransform toAffineTransform()

Overrides:

toAffineTransform in class AAffineTransform

toMutableTranslation

public ATranslation toMutableTranslation()

isIdentity

public boolean isIdentity()

Returns true if this transform is an identity transform

Overrides:

isIdentity in class AAffineTransform

equals

public boolean equals(ATranslation a)

equals

public boolean equals(AAffineTransform a)

Overrides:

equals in class AAffineTransform

inverse

public ATranslation inverse()

Description copied from class: ATransform

Return the inverse of this transformation if possible

Overrides:

inverse in class AAffineTransform

Returns:

isSquare

public boolean isSquare()

Description copied from class: ATransform

Returns true if the transform is square (same number of input and output dimensions)

Overrides:

isSquare in class ATransform

Returns:

isInvertible

public boolean isInvertible()

Description copied from class: ATransform

Returns true if this transform is invertible

Overrides:

isInvertible in class AAffineTransform

hashCode

public int hashCode()

Overrides:

hashCode in class AAffineTransform
