Constructor Details

AffineTransform2D

public AffineTransform2D(Matrix2x2 inputMatrix,
 Vector2D inputVector)

Create a type of affine transformation.

Parameters:

inputMatrix - A matrix Matrix2x2 which defines the matrix-multiplication part of the affine transformation.

inputVector - A vector Vector2D which defines the vector-addition part of the affine transformation.

Method Details

transform

public Vector2D transform(Vector2D point)

Multiplies the matrix Matrix2x2 matrix by the vector Vector2D vector and adds the vector Vector2D point.

Specified by:

transform in class Transform2D

Parameters:

point - The vector Vector2D which transformations are performed on.

Returns:

A new vector Vector2D which represents a point on a plane. The point represents a new step in the creation of fractal.

getMatrix

public Matrix2x2 getMatrix()

Getter method to use with ChaosGameFileHandler.

Returns:

The matrix for the transformation.

getVector

public Vector2D getVector()

Getter method to use with ChaosGameFileHandler.

Returns:

The vector for the transformation.
