A colloquium sponsored by The Institute for Computer Research, the Computer Science Club, and the Computer Graphics Laboratory A Napkin's Nightmare or A Funny Thing Happened on the Way to Expo '86 by David Martindale of Computer Animation Centre National Film Board of Canada Abstract ``TRANSITIONS,'' the world's first 3D IMAX* film, was seen by two million people at Expo '86 in Vancouver. This 22-minute film contained about 2 minutes of animation that was produced by the Computer Animation Centre of the NFB. This is a very informal talk about the experiences and lessons of making that film, and about computer graphics in the ``real world.'' IMAX is a spectacular but unforgiving format - each image covers ten times the film area of 35mm films. To obtain acceptable sharpness on screen, all animation was computed at a resolution of 4096 x 3072 pixels. (Computer graphics on television is typi- cally 640 x 485). A total of about 5000 images were needed. The speaker will discuss the algorithms that had to be developed to permit calculating and filming these images, the problems of storage (where do you put 50 gigabytes of data?), and some things that caught us by surprise. The talk will begin with a brief in- troduction to IMAX and 3D technology. * ``IMAX'' is a registered trademark of IMAX Systems Corporation.
