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

Render part c class hierarchy.svg

Continue editing files in the render/assignment directory.

Code to Implement

Bounds

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 Point2ds.

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 Point2ds.

EquilateralTriangle

file: src/main/ruby/render/assignment/equilateral_triangle.rb Ruby logo.svg
class: Rectangle
superclass: EquilateralTriangle
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 Point2ds.

BezierCurve, Chord, Image, Text

Imagine what it would be like to define calculate_local_bounds for each of these classes.

CompositeTransform

calculate_local_bounds

Scene

calculate_bounds

ConvexPolygon

render_transformed

calculate_local_bounds
