I don’t often take long strolls down memory lane, but there’s one tale of technology that I would like to share. It’s a story about how hard computer animation used to be.
From 1978 till 1989 I worked as a mechanical engineer for a defense contractor, then called Hughes Aircraft Company. I worked in an organization responsible for the design of gimbaled systems for optical telescopes and radar sensors. A gimbal is a mechanism designed to allow the sensor in question to be rotated both horizontally and vertically (or as we say in the business, in azimuth and elevation) to point the sensor in a certain direction. When I started at the company, we did all of the design on drafting boards with pencils and paper. Kids, go ask your parents (or grandparents) what a drafting board is.
