Render Part C Assignment
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 | |
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 | |
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 | |
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
.

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
