Simple simulation of double pendulum's motion, that uses Runge-Kutta 4 algorithm to solve motion equations. Custom, minimalistic image class is used to render animation frames, that then can be converted into video using ffmpeg.

In order to build this application run the following command:

cmake .
make

Make a directory for animation frames:

mkdir frames

Run:

./app

And to make a video from produced frames:

ffmpeg -framerate 30 -i frames/frame%d.ppm -c:v libx264 -pix_fmt yuv420p -crf 23 output.mp4
