I’ve never read Slapdash, so thanks Scott Elofson for the heads up on this.
“Anonymous” has got to be a former RPI student. This work was done from 1977-87 at the Video Synthesis and the Image Processing Labs. It started on a PDP-8L and migrated in 1983 to an Apple II. That made it portable, and it was shown in live demos all around like at SIGGRAPH (’86 & ’87) and at the Museum of Modern Art of the City of Paris (’83-’84). There are videos, so I’ll find and post some. More to come from me too, because in ’84 I started doing the 3D acquisition another way. That led to patents, NSF and NASA grants, and now a startup. TD
