getDimension

public int getDimension()

Description copied from interface: InvertibleTransform

Returns the dimension of the space which this transform operates on.

Specified by:

getDimension in interface InvertibleTransform<Affine2D_F64>

Returns:

space's dimension

createInstance

public Affine2D_F64 createInstance()

Description copied from interface: InvertibleTransform

Creates a new instance of the same SpecialEuclidean as this class.

Specified by:

createInstance in interface InvertibleTransform<Affine2D_F64>

Returns:

A new instance.

set

public void set(Affine2D_F64 target)

Description copied from interface: InvertibleTransform

Assigns 'this' to the value of target.

Specified by:

set in interface InvertibleTransform<Affine2D_F64>

Parameters:

target - The new value of 'this'.

concat

public Affine2D_F64 concat(Affine2D_F64 second,
                           Affine2D_F64 ret)

Description copied from interface: InvertibleTransform

Computes a transform which is the equivalent to applying 'this' then the 'second' transform.

For example:

Point A = tran2( tran1( A ) );
Point A = tran12( A );

where tran12 = tran1.concat( tran2 , null );

NOTE: 'second', 'result', and 'this' must all be unique instances.

Specified by:

concat in interface InvertibleTransform<Affine2D_F64>

Parameters:

second - The second transform which is applied. Not modified.

ret - A transform which is equivalent to applying the first then the second. If null then a new instance is declared. Modified.

Returns:

The equivalent transform.

invert

public Affine2D_F64 invert(Affine2D_F64 inverse)

Description copied from interface: InvertibleTransform

Computes a transform which is the inverse of this transform. The 'this' matrix can be passed in as an input.

Example:
Point A = tran(B);
Point B = inv(A);

where inv = invert( tran );

Specified by:

invert in interface InvertibleTransform<Affine2D_F64>

Parameters:

inverse - Where the inverse will be stored. If null a new instance is created. Modified.

Returns:

The inverse transform.

reset

public void reset()

Description copied from interface: InvertibleTransform

Sets the transform to its initial state of no transform.

Specified by:

reset in interface InvertibleTransform<Affine2D_F64>

copy

public Affine2D_F64 copy()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
