I am trying to draw the following situation with a graphics program, but could not because I do not know how to create the animation. Your help is therefore greatly appreciated.
So my picture consists of two objects:
At the bottom of the page is a torus with an animated "irrational" line surrounding the torus
likes this video
And above this torus a pipe (cylindrical line)
Simultaneously animated with the packaging line in the tours. (For example, like this video
but in our situation the pipe does not close!)
Thanks in advance!
