Sorting Animations

This C program produces videos for various sorting algorithms. Points are ordered by hue, and the distance from the center indicates a point's distance from its correct position. The original idea for this animation comes from w0rthy.

To create a video, pipe standard output into a video encoder:

$ ./sort | x264 --fps 60 -o video.mp4 /dev/stdin

Some media players can play raw video from standard input as well:

$ ./sort | mpv --no-correct-pts --fps=60 -

Others need help from mjpegtools (ppmtoy4m):

$ ./sort | ppmtoy4m -F60:1 | vlc -

The program's output is a bunch of concatenated images, one per frame, in PPM format.
