I‘m really glad it works for you and thanks a lot for sharing! Watching this video is satisfying to me, too!

Haven't tried but it might work. Is the part at the same resolution as the whole? Same-to-same or same-to-similar sample? Consider posting photos & details here: github.com/danionella/w...
Warpfield determines transformations between 3D volumes only, and can apply them to 3D volumes and coordinates.

Peering through MRI scans of fruit and veg, part 1
What do you see when you pass fruit and vegetables through an MRI scanner? And how many animated GIFs can you make?

Who wouldn't want to do that?
Unfortunately I don't think this would be a good tool for it. You probably need many discontinuities and flips to go from car to artichoke. Although not (yet) strictly enforced, this library tends to generate smooth fields and local displacements.

Nice! Do you expect the same effect for 2D and 3D interpolations?

Could you add me, please?

Next stop: brain. We are interested in brain-wide circuits underlying acoustic communication (from hearing to sound production), which we currently study with the volumetric whole-brain microscope developed by @mh123.bsky.social and Jörg Henninger. www.nature.com/articles/s41...

How do they know who is talking? Sound localization by fish was long considered physically impossible, and yet it was shown behaviorally. With underwater sound illusions and laser vibrometry, Johannes Veith and @tomchaigne.bsky.social identified an underlying mechanism www.nature.com/articles/s41...
The mechanism for directional hearing in fish - Nature
A study demonstrates that the fish Danionella cerebrum is able to discriminate the direction of sound by comparing the relative phase of pressure and particle motion.

Danionella clicks can reach 140 dB! How can a tiny fish under 12 mm produce such unusually loud sounds? Verity Cook found a unique sound production apparatus that shoots a specialized cartilage against the swim bladder, accelerating at over 20000 m/s^2: www.pnas.org/doi/10.1073/...
