And obviously as it's an animation engine for UI it had all easing function you want. Including some parametrizable Bezier, Physics Spring or even a custom callback for the creative ones.

The non trivial part was support of text and path. I built properly the inverse CDF to be able to have constant speed along a path (bezier, quadratic, ...)

Lot of small features but I try to keep the front end simple. We have tween, clip.
We a clip we can easily create sequences. I was inspired AnimeJS (by @juliangarnier).

I didn't have time to fully update the code for #GPUZen3 on #Unity 6 LTS. So for now I'm sharing illustrations code and Jacobian derivation notebook (#Mathematica).
Plus some illustrations I did not use in the book chapter.

And the final boss of geometrical LOD.
Preserving the appearance of this one can be challenging, I have some ideas, but nothing trivial. I'm open to any idea.
