Motivation
We will recursively generate some images with the Racket Image Library.
Code To Investigate
placement
shapes
Spacer
; fully transparent rectangle (define (spacer-rect w h) (rectangle w h "outline" (color 0 0 0 0))) ; fully transparent image the size of img (define (spacer-image img) (spacer-rect (image-width img) (image-height img)))
Sierpiński
| file: | src/main/racket/sierpinski_and_cantor/sierpinski.rkt |  |
| functions: | sierpinski-triangle sierpinski-carpet |
Triangle
(define (sierpinski-triangle side-length n) (raise 'not-yet-implemented #t))
|
|
|
|
|
| n=0 | n=1 | n=2 | n=3 | n=4 |
Note: this has a remarkably clean solution. It is almost as if the Racket Image Library was created to build the Sierpiński Triangle.
Carpet
(define (sierpinski-carpet side-length n) (raise 'not-yet-implemented #t))
|
|
|
|
|
| n=0 | n=1 | n=2 | n=3 | n=4 |
Cantor
| file: | src/main/racket/sierpinski_and_cantor/cantor.rkt | |
| functions: | cantor-stool |
Stool
(define (cantor-stool width height n) (raise 'not-yet-implemented #t))
|
|
|
|
|
| n=0 | n=1 | n=2 | n=3 | n=4 |
Note: you have been provided with a function which draws a red rectangle outlined in blue.
(define (brick w h) (overlay (rectangle w h "outline" "blue") (rectangle w h "solid" "red") ) )
