"Just after World War II my brother and I were constantly excited by a
future world. We sort
of expected it to happen before the 1940's were past."
John whitney Sr's analogue computerwas a twelve-foot-high device
capable of producing complex,
yet beautiful graphic designs. Unlike the digital computer which requires the
processing of mathematical
equations as its input, Whitney's analogue computer must have its information
ready before it is processed,
meaning that template must be created.
The "information" or image source was hi-con kodalith film negatives.When
manipulated by the cam machine in a precise orbital motion --with an added
movement differential the result is
animation. His insight was to harness the cam and ball integrators (formerly
used as dedicated equation solvers for the gun fuse timing) as a source of
differential motion. That is the key he later continued to use with the
digital computer programs. See RDTD.
Works such as Arabesque or
Catalogue, must first have
the images drawn, photographed, and pasted together before processing. Images
could be a simple pattern or
something more complex like a field of hand-painted dots.
