I have been working for a while on a way to generate mathematical curves in synfig using converters for an animation . I have been quite successful and thought that while I prep a tutorial, I could share the file here because of my schedule.
The curve generated is a lemniscate of Bernoulli. Find out more here Lemniscate of Bernoulli - Wikipedia (Focus on the parametric equations)
P.S. No keyframes was involved in this animation. Lemniscate.sifz (4.0 KB)
I noticed that if we reduce the step of the duplicate layer we can get a smooth line, although itās taxing on performance. Also, you can animate āSCALEā parameter to make the line gradually disappear. Hereās how it looks:
Another thing you can do is to replace circle with something else. For example, here I replaced it with an outline and motion blur:
Doesnāt look that good, but I didnāt spend much time adjusting. Some cool effects sure can be made.
Overall, awesome stuff! It was fun playing with it.
