Details

See simone_attractor.cpp for more about this attractor. Here we use the same method, but animate by letting the \( a \) and \( b \) parameters vary. The following commands are used to combine the results into movies.

          ffmpeg -y -framerate 15 -i simone_attractor_bmovie_%4d.tiff -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" -c:v libx264 -crf 10 -b:v 0 -preset veryslow simone_attractor_bmovie_100_crf10.mp4;
