A short blog post on doing cubic interpolation of quaternions:

Another great post Daniel. FIFA23 uses a very similar technique for cubic interpolation in replay. It makes a huge difference.

Nice! Looks brilliant!

QQ: why quaternions are not exponential maps? Does it boil down to #FLOPS/op? (i.e. yes, it's over-parameterized, but interpolation is cheaper)

That's the simple answer: no easy way to compose exponential maps other than converting them to quaternions and back (AFAIK). Full answer is probably a bit more nuanced - definitely pros and cons to both.

Applying to the pufferlib mascot when I get some spare time, thanks

Are you using raylib?! That ui font seems familiar.

Yes this is using raylib!

We tried, but the cubic spherical interpolate solution in #GodotEngine we derived was ugly. Hope there's a way to improve it.

This is great! btw, is your visualisation (especially the gui slider) using Raylib or something else?

Yes it's raylib, and raygui!
