50000 Rectangles #23

40000 rectangles.

(Continued from 50000 Rectangles #22.) A typical IFS fractal requires many iterations of the chaos game. Each chaos-game point is used to build a histogram. There are as many buckets in the histogram as pixels in the image. More if there is oversampling. If color is used to represent density, many buckets need to be hit many times. One hundred million iterations or more may be necessary for a high resolution color IFS image.

These images do not require as many iterations as a typical IFS or flame fractal. Each point generates a rectangle, so the screen fills quickly. Ten thousand iterations is usually adequate.
