Sierpinski Assignment

Motivation

We will recursively generate some images with the Racket Image Library.

Code To Investigate

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)))

Triangle

Sierpiński 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.

Carpet

(define (sierpinski-carpet side-length n)
  (raise 'not-yet-implemented #t))

n=0	n=1	n=2	n=3	n=4

Cantor

Cantor set

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
