Image West had been in business several years when I first came there in 1980 as a maintenance engineer.
The company had been bought from Computer Image's bank at a bargain,
and had been operating successfully for several years.
They were in the midst of splitting from a Canadian parent company, called Omnibus.
(John Pennie, the other owner of Omnibus went on after the split to form
Omnibus Computer Graphics in Toronto.)
Cliff Brown, (shown at left in an image captured from videotape)
who was then president of Image West, asked me to recommend some options for
future development directions.
In 1981, there were few options.
Digital image-making state of the art was a PDP-11 and a $50,000 framebuffer, and
a bunch of assembly or FORTRAN programmers hacking away from scratch.
Triple-I, NYIT, and MAGI were about the only people going that route.
Image West had always had the advantage of "Real Time", meaning that despite
the limitations of the analog rescan technology, it could run right before your eyes,
and be adjusted on the fly.
Its big downfall was complete lack of repeatability, due to all those knobs and
patch wires.
After reviewing all the options, Cliff and I decided a good approach would be
to build a system based on the analog rescan technology, but using digital
computers to track and store the setups needed to repeat a job.
I did not realize at the time how large a project this would be.
Here is a closeup of the CRT section of one bay in the final version.
If you look carefully, you can make out the subscreen CRT.
Rather than the awkward protruding camera like Scanimate had, I chose to
fold up the whole optical path using front-surface mirrors.
The whole thing fit into a rack-mounted slide system, and plans were
to introduce filtration mid-path at some later point.
The CRT was scanned by a COHU camera, which turned out to be
a very poor performer.
Later plans were to take an old studio camera and split the individual
red, green, and blue electronics out to allow registered RGB
signals to be animated.
Alas, advances in digital framebuffer technology just did a better job
of storing an image than the face of a CRT.
Also, as it turned out, our high-resolution CRT was TOO high-res!
The Scanimate had used that big fat point to fill in a lot of space
between scan lines.
This was the VersEFX control console, manned here by Jim Ryan,
the project software engineer.
The bay came out very much like the original artists rendering above.
Unfortunately, despite having shifted all costs over to the SFP, Image West
ran into financial difficulties, and the only system built was shipped to France.
Peter Koczera claims he went over and that the system was working and they did
some interesting things with it, but it was never completed, partly because
the design goals were moving targets throughout its development.
I learned a lot about managing projects of this size, most specifically
how fast technology can change, often before a big design can be completed.
It also became apparent how quickly a small company can be swamped trying
to do R&D on this kind of level.
