I don't see any math, only visualization, where is the mathematical concepts and equations explained again?

Hi suyash, take a look at the README for information on what all the little graphs represent: https://github.com/diegomacario/Animation-Magic/blob/main/RE...

There's also a button in the controls that allows you to open the README. Thank you!

I agree.

For example I don't see a link between a given graph and one particular joint.

The README says each joint has (3 + 4 + 3) values but I only see graphs with 4 curves.

Ideas:

* allow to select a particular joint to only view the graphs related to that joint

* add titles to each graph

* allow to pause the animation, change the speed

Hi dolmen!

In the "Implementation Details" section at the bottom of the README I actually explain why I only display 4 curves instead of 10, and you can change the speed of the animation and pause it using the "Playback Speed" slider. If you set it to 0, the animation will pause.

Thanks for your suggestions about being able to select joints and displaying titles. I hope to improve things in the future!
