Revision as of 02:06, 14 November 2022
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 drawings directory.
Contents
Code to Implement
Bounds
file: | src/main/ruby/drawings/bounding_box.rb | ![]() |
class: | BoundingBox | |
superclass: | Object | |
methods: | initialize(min,max) min() min=(min) max() max=(max) |
Note: be sure to require_relative 'point2'.
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/drawings/transform.rb | ![]() |
class: | Transform | |
superclass: | Object | |
methods to evolve: | Ø | |
methods to add: | move(direction,amount) 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.
bounds
invoke untransformed_bounds
and transform the returned bounds by x and y.
NOTE: untransformed_bounds
is abstract. it must be defined by the subclasses.
Rectangle
file: | src/main/ruby/drawings/rectangle.rb | ![]() |
class: | Rectangle | |
superclass: | ColorTransform | |
methods to evolve: | Ø | |
methods to add: | untransformed_bounds | |
methods to remove: | Ø |
untransformed_bounds
Returns an instance of Bounds specified by min and max instances of Point2
.
NOTE: this method must be private.
Ellipse
file: | src/main/ruby/drawings/ellipse.rb | ![]() |
class: | Ellipse | |
superclass: | ColorTransform | |
methods to evolve: | Ø | |
methods to add: | untransformed_bounds | |
methods to remove: | Ø |
untransformed_bounds
Returns an instance of Bounds specified by min and max instances of Point2
.
NOTE: this method must be private.
EquilateralTriangle
file: | src/main/ruby/drawings/equilateral_triangle.rb | ![]() |
class: | EquilateralTriangle | |
superclass: | ColorTransform | |
methods to evolve: | Ø | |
methods to add: | untransformed_bounds | |
methods to remove: | Ø |
untransformed_bounds
Returns an instance of Bounds specified by min and max instances of Point2

class: | BezierCurve | |
superclass: | ColorTransform | |
methods to evolve: | Ø | |
methods to add: | untransformed_bounds | |
methods to remove: | Ø |
untransformed_bounds
Contemplate for a moment how you would build this method and then raise an error and move on.
NOTE: this method must be private.
def untransformed_bounds raise StandardError.new("not yet implemented") end
Text
file: | src/main/ruby/drawings/text.rb | ![]() |
class: | Text | |
superclass: | ColorTransform | |
methods to evolve: | Ø | |
methods to add: | calculate_local_bounds | |
methods to remove: | Ø |
calculate_local_bounds
Contemplate for a moment how you would build this method and then raise an error and move on.
NOTE: this method must be private.
def untransformed_bounds raise StandardError.new("not yet implemented") end
CircularSegment

Note: You will need to add this file. Starter code:
require_relative 'color_transform' require_relative 'point2' class ConvexPolygon < ColorTransform end if __FILE__ == $0 require_relative '../core/render_app' points = [ Point2.new(0.85, 0.0), Point2.new(0.1, 0.25), Point2.new(0.0, 0.45), Point2.new(0.15, 0.7), Point2.new(0.65, 1.0), Point2.new(0.95, 0.95), Point2.new(1.1, 0.75) ] app = RenderApp.new(ConvexPolygon.new(points, x: -0.5, y: -0.5, color: Color.new(1, 0, 0))) app.main_loop end
initialize
Accept a required parameter points which is an array of Point2s.
Accept keyword parameters for x: 0, y: 0, and color: nil to the constructor and pass them to the superclass.
NOTE: Be sure to not override render. Implement the render_transformed method instead.
