An Application of Hybrid Curve Generation: Cartoon Animation by Electronic Computers
Conference paper from the 1967 Spring Joint Computer Conference describing two hybrid-computer methods for automating cartoon animation. The analog method generates pictures on a CRT by modifying circles via transformation circuits on the Hitachi ALS-2000; the hybrid method reads animator-drawn keyframes into a digital computer, calculates tangents by parabolic approximation, and uses analog elements to interpolate smooth curves between frames. Mathematical details of both linear and similarity-based frame interpolation are provided.
