I want to make educational videos related to math and physics, I can handle the visuals of physics with Adobe AE, but the math part of it needs to be there too, so if anybody has some has some suggestions, please leave them.
What I want:

  • Good looking animations (Youtube)
  • The ability to graph functions, fully and partially (for ex, the arc of a circle, which increases over time), with the options of having a visible grid/axes (This one must be switchable for both, since there are times when there's no need for both, and times when both are needed)
  • The output should be in a common format (.mkv, .mp4, img sequence or something)

  • I did something like that in Mathematica. You have to pay for it though. – Kaster Jun 25 '17 at 00:48
  • @Kaster I'm not really familiar with Mathematica, but isn't it a CAS? – Shahe Ansar Jun 25 '17 at 00:58
  • Mathematica can animate. Also, 3blue1brown animates his videos in python and releases the source for all his animations. Might be worth a look. I made this gif in MATLAB a while back, I'm sure it can be done in Octave as well. Basically, there are lots of options. – Arthur Jun 25 '17 at 01:03
  • @Arthur I actually took a look at his tools, they're fairly complex, and a bit too inflexible for what i need. As for MATLAB, can you tell me if it's possible to change background colors and other visuals? Since I AM animating for a video. – Shahe Ansar Jun 25 '17 at 01:28
  • @Arthur Also, are the same features available in Octave? That seems more to my liking (since I don't really have a budget, spent everything on Adobe's license) – Shahe Ansar Jun 25 '17 at 01:31
  • One option is using WebGL and a javascript library that helps out. For example, the MathBox Library is pretty cool and high level. https://acko.net/blog/making-mathbox/ If you want more control over what you are animating, try ThreeJS. The benefit of using these tools is that they are free, require minimal setup, and all you need is a browser to run them – Jonathan Davidson Jun 25 '17 at 01:47
  • You can see many mathematical animations I've made in Matlab in the links provided in my profile. – Cye Waldman Jun 25 '17 at 02:38
  • Octave is meant to be a free MATLAB clone. Or, almost meant to be one (I think they say they want to be better than MATLAB, which necessarily means different in some respect). Most things MATLAB can do, Octave can do. As for the python tools, I haven't actually looked at them myself, so you might be right. – Arthur Jun 25 '17 at 07:05
  • As for what's possible, simple graphics changes like background color and axes should be possible and quite easy (although background color in particular depends on what backend you use; gnuplot can't change background color, while openGL can from what I can tell from a quick google search). More complicated graphic stuff, like changing the texture of a surface, is probably a lot harder and the possibilities more limited. – Arthur Jun 25 '17 at 07:47
  • @JonathanDavidson The options you provided seems enticing, but do they have a method to convert the output into a common format? – Shahe Ansar Jun 27 '17 at 19:22
  • You need to elaborate to what context. There are some code libraries that convert webgl javascript into a gif file. – Jonathan Davidson Jun 30 '17 at 03:43
  • @JonathanDavidson The original question should answer that – Shahe Ansar Jun 30 '17 at 05:23
  • you are right. Well couldn't he just use OBS to record his screen while webgl applications are running, and convert it to whatever format he wants? – Jonathan Davidson Jun 30 '17 at 05:24
  • @JonathanDavidson No other, more elegant solution? – Shahe Ansar Jun 30 '17 at 05:37
  • None that i can think of. I looked up ways in which the webgl programs could be converted to other video formats, and it seems you are going to have to rely on some github project for the conversions. – Jonathan Davidson Jun 30 '17 at 05:40
  • @JonathanDavidson Yeah, I'll probably just use openframeworks.. – Shahe Ansar Jun 30 '17 at 05:51
