Would any cool phenomena happen if you try to project these on to the three planes?

I believe an intersection with any plane would give you Julia sets over the complex numbers. Projection on the other hand could be cool but would probably be pretty noisy. Quaternions are already 4D so I’m kind of curious - is this animation a projection or a cross section?

Also I want your shader! It looks like you’ve actually found the right balance to visualize what a volumetric solid is doing on the inside, and for the longest time I’ve been looking for a way to properly visualize my twist animation applied to completely solid space.

I’ll share my shader in exchange for your spin thingy!

Deal! Pseudocode transforms sample p with center c radius range l-h at time t. deform(p, c, l, h, t) { r = |p - c| k = smoothstep(saturate((r - l) / (h - l))) q0 = quaternion(0, sin(t), 0, cos(t)) q1 = quaternion(1, 0, 0, 0) q = slerp(k, q0, q1) return (p - c) * q + c }

Conceptually t rotates the axis and then you blend the amount of rotation between nothing and 180 by finding where the point falls relative to the radius range. It should match what I illustrate here, if you just take the frames where it pauses.https://twitter.com/JasonHise64/status/1316081015236902912 …
