Experimenting with computer films


16 mm Computer Generated Films 1972-1975


During my one-man show at the Museum of Modern Art in Paris in 1971, I met the CEO of C.G.M (La Companie Generale de Micromatique), a data storage and preservation company, which specialized in micro films. He invited me to experiment on their brand new machine DATAGRAPHIX 4460 to make computer animations. I gladly accepted and during the next 4 years I made several short computer films. It was a very painful experience since the process was very slow and the turnover dragged out over many months.

For the film, each frame was drawn in high resolution with a light beam directly from the computer onto 16mm film to create the animations.



The original 16 mm film (around 4 min), 'Cubic Limit' (1973-1974), is now converted into digital format. The quality of the copy is not good, but nevertheless shows the film from that time. It is installed on youTube with a header and trailer. Images from this film were published in the catalog "Cubic Limit", 1975 (see below).

The earlier 16mm film (around 4 min), 'Square Roots' (1972-1973), was my first attempt to make a computer movie. I abandoned this short film because I felt it was too narrative. Subsequently I made the more abstract film 'Cubic Limit' (above). Nevertheless, although unedited, this is a short amusing film which has some of the 2-D elements which I later used in 'Cubic Limit' in 3-D.

This short 16mm film (around 1 1/2 minutes) is 'Transition I' (1972-1973). As an inauguration gift, I transformed a sketch of the new city hall into the coat of arms of my hometown Pforzheim. Images from this film are published in the book: Pforzheim 1973 (see below).

This very short footage (around 1/2 minute) from 1972 is a study of a cube transforming to random points and back.

This footage 'Complimentary Cubes' (around 5 1/2 minutes), from 1973 - 1974, was originally written for the film "Cubic Limit" but was not used in the film. It shows 2 sequences of all the combinations of 2 rotating cubes, one with 'n' edges and the other with '12 minus n' edges. Images from this film were published in the catalog "Cubic Limit", 1975 (see below).
