Hello,
I am new here. But I follow this forum for a while, as well as the website formerly named "eusebeia". I'm interested in making 3D animations. I use POV-Ray, the R package rgl, the Python package pyvista, three.js, and Asymptote. Here is my youtube channel, it contains some animations, and for almost each one, a link to the code is provided. You will recognize some animations of the member 'ICN5D'. Here is my blog. A couple of posts are about 4D geometric objects. My background is mathematics and now I'm working as a programmer and statistician. I'm glad to join this forum.
