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
Transform
file: | src/main/ruby/render/assignment/transform.rb | |
class: | Transform | |
superclass: | Object | |
methods to evolve: | - | |
methods to add: | move(direction,amount) calculate_bounds() |
|
methods to remove: | - |
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
Rectangle
file: | src/main/ruby/render/assignment/rectangle.rb | |
class: | Rectangle | |
superclass: | ColorTransform | |
methods to evolve: | ' | |
methods to add: | calculate_local_bounds | |
methods to remove: | ' |
calculate_local_bounds
BezierCurve, Chord, Ellipse, EquilateralTriangle, 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
