I noticed but could not identify:
07:13 calligraphic graphics system with hidden line removal. Could be
an Evans & Sutherland LDS-1, but might be something earlier.
I've seen this system in several NASA films, but I've never been
able to get any information on the hardware used.
I scratched my head at that myself. There's a slant to the frame not too different
than the perspective you'd get if you had a movie camera pointed at some graphics
terminal.
Several technologies I know of at that time, would not result in any such slant:
State of the art for several scientific application in that area, involved pen plotters
(black ink on white paper) transferred to photographic negative movie film. (White image
on black).
A slightly cheaper approach (used extensively in my area of academia) was line printer
paper plots transferred to movie film (again often in negative). Sub-character resolution
was possible through choice of characters (not dissimilar to "ASCII graphics"
although I know the movies were made using IBM and EBCDIC!)
There was talk of direct-laser-to-film but I never saw it.
