What is the Future of Focus-Stacking?

Early, prototypical equipment at this point. Will be interesting to see developments over the next several years.

It feels like there should be an easier way like constant movement scanning versus individual images.

thank you for the sites but i was unable to find any information about how the scan was performed.
Reading between the lines and comparing it to scanning methods 20 years ago i got the impression they perform a vertical line scan, adding distance per sample point and then rotate a fraction of a degree and repeat. The cloud is then assembled into a crude surface mesh.
Am I in the ball park?

A $500 camera and free software will outperform any $10,000 scanner out there by an order of magnitude with ease.
