Csuri - Digital Plotting plotting

Hummingbird, 1967

We completed a ten minute computer animated film entitled Hummingbird. The subject was a line drawing of a hummingbird for which a sequence of movements appropriate to the bird were outlined. Over 30,000 images comprising some 25 motion sequences were generated by the computer. For these, selected sequences were used for the film. A micro-film plotter recorded the images directly to film. To facilitate control over the motion of some sequences, the programs were written to read all the controlling parameters from cards, one card for each frame. Curve fit or other date generating programs were used to punch the parameter decks. We also built a windowing option into our plot subroutine.
