   >What could also be nice is an option to eliminate the first few thousand iterations (yellow box and red start) to only show the stable orbits. That’s a good idea, will try it.

   It's doing a perspective rendering. You can change the camera FOV in the controls (which approaches orthographic as the FOV goes to zero). I could add a specific orthographic mode though perhaps.

   This app is pretty decent: https://www.falstad.com/vector3dm/ Looking at the source code, indeed many of the magnetic fields are computed via the Biot-Savart law, though some interesting ones are not. I might try rende

   OK, good suggestions, i'll look into improving it. Cheers!

   Thanks for the suggestion, that does look like a nice way to visualize the structure of the phase space. I'm not sure it's easy to implement this though, as it requires first solving for the equilibrium points of the flow, which i

   The following is a visualization of electric field lines (for a "quadrupole" of charges): https://twitter.com/jamportz/status/1079777103892135936 https://tinyurl.com/y859v78t For magneti

   It should work if WebGL 2 is supported, though possibly there could be missing extension issues. I haven't tried it on Android, will try to do so. I'm not sure it will be usable anyway on a mobile device ( https://github

   They are basically visualizations of the "integral curves" defined by the vector field. https://en.wikipedia.org/wiki/Integral_curve You can think of the vector field as the definition of a differential equ

    Hi Sjeiti, I wrote this, thanks for the comments. Agreed it needs some optimization. The reason the attractor gets recalculated when rotating, is that there is actually no geometry at all.. This is different from the approach used in e.g.
