Back in the late 90's when Prof. Helmut Dersch released his Panorama Tools there was an explosion of people creating full spherical VR panoramas for the first time.

Actually, most of the credit for popularizing the idea belongs to IPIX -- which was an "evil" company in that they charged per-image fees and aggressively protected lens transformations that many of us believed should never have been patentable. Helmut's software, first released in 1998, was a beautifully done open source project, which got into trouble because it allowed people to work around IPIX. Suffice to say that now IPIX is gone and Panorama Tools is the core of many wildly used tools.

We used Helmut's math for things like the 360-degree interactive pan+zoom live video we showed at IEEE/ACM Supercomputing 1999, which had an autonomous wheeled vehicle capture back-to-back 185-degree image pairs from tethered Nikon 950s....

... We used a Coolpix camera which was quite nice at the time (this was 1999 or 2000).

Probably the Nikon 950 and FC-E8 fisheye converter -- that's what I used. In fact, I still have one tethered and mounted on the ceiling of my supercomputer machine room.

I saw one macro panorama created using this method that was taken with the ball inside a running shoe, giving a 360 degree ant's-eye view of the whole interior, very surreal at the time.

Just tried it with a modern $3 USB endoscope camera. Not great....

I remember the excitement of making nodal point rotation mounts from scratch to be able to take sphericals back then (on film). Now, you can buy ready made kits complete with lens, and nearly every real estate website has 360 VRs.

Can't really do spherical stitch using film. There were a lot of alternatives. For example, there were various cylindrical pan cameras that used geared rotating slit exposure systems....
