In this studio we will evolve our code from Render_Part_B_Assignment to add new methods and a new class.

Continue editing files in the render/assignment directory.

Code to Implement

Bounds

file: src/main/ruby/render/assignment/bounds.rb Ruby logo.svg
class: Bounds
superclass: Object
methods: initialize(min,max)
min()
max()

Note: min and max should be instances of Point2.

Note: You may wish to use Ruby's convenient Struct construct.

Transform

file: src/main/ruby/render/assignment/transform.rb Ruby logo.svg
class: Transform
superclass: Object
methods to evolve: Ø
methods to add: move(direction,amount)
calculate_bounds()
methods to remove: Ø

move

the move method will accept two parameters: direction and amount.

direction can be one of four symbols

:left
:right
:up
:down
left corresponds to translating along the negative x axis
right corresponds to translating along the positive x axis
down corresponds to translating along the negative y axis
up corresponds to translating along the positive y axis

any other value for direction should raise an ArgumentError.

calculate_bounds

invoke calculate_local_bounds and transform the returned bounds by x and y.

NOTE: calculate_local_bounds is abstract. it must be defined by the subclasses.

Rectangle

file: src/main/ruby/render/assignment/rectangle.rb Ruby logo.svg
class: Rectangle
superclass: ColorTransform
methods to evolve: Ø
methods to add: calculate_local_bounds
methods to remove: Ø

calculate_local_bounds

Returns an instance of Bounds specified by min and max instances of Point2.

Ellipse

file: src/main/ruby/render/assignment/ellipse.rb Ruby logo.svg
class: Ellipse
superclass: ColorTransform
methods to evolve: Ø
methods to add: calculate_local_bounds
methods to remove: Ø

calculate_local_bounds

Returns an instance of Bounds specified by min and max instances of Point2.

EquilateralTriangle

file: src/main/ruby/render/assignment/equilateral_triangle.rb Ruby logo.svg
class: EquilateralTriangle
superclass: ColorTransform
methods to evolve: Ø
methods to add: calculate_local_bounds
methods to remove: Ø

calculate_local_bounds

Returns an instance of Bounds specified by min and max instances of Point2.

BezierCurve

file: src/main/ruby/render/assignment/bezier_curve.rb Ruby logo.svg
class: BezierCurve
superclass: ColorTransform
methods to evolve: Ø
methods to add: calculate_local_bounds
methods to remove: Ø
  def calculate_local_bounds
    raise :not_yet_implemented
  end

Text

file: src/main/ruby/render/assignment/text.rb Ruby logo.svg
class: Text
superclass: ColorTransform
methods to evolve: Ø
methods to add: calculate_local_bounds
methods to remove: Ø
  def calculate_local_bounds
    raise :not_yet_implemented
  end

Chord

file: src/main/ruby/render/assignment/chord.rb Ruby logo.svg
class: Chord
superclass: ColorTransform
methods to evolve: Ø
methods to add: calculate_local_bounds
methods to remove: Ø
  def calculate_local_bounds
    raise :not_yet_implemented
  end

Image

file: src/main/ruby/render/assignment/image.rb Ruby logo.svg
class: Image
superclass: Transform
methods to evolve: Ø
methods to add: calculate_local_bounds
methods to remove: Ø
  def calculate_local_bounds
    raise :not_yet_implemented
  end

CompositeTransform

calculate_local_bounds

Scene

calculate_bounds

ConvexPolygon

render_transformed

calculate_local_bounds

Testing Your Solution
