“Before the days of digital computers, calculations were done with analog circuitry. Instead of typing commands, you wired things together and adjusted knobs. When digital computers came along, graphics developers delighted in the ability to make trillions of precise computations, resulting in the very clean imagery we’ve come to associate with modern 3D graphics.

Only recently have the fastest modern computers with highly optimized software and hardware pipelines become capable of calculating and simultaneously displaying a complex sequence of animation in real time. But 20 years ago, it was just this ability that made the dozen or so Scanimate computers a unique milestone in the history of computer graphics.” -Dave Sieg’s intro to his article on the Scanimate
