One of the first professional projects was a graphic plotting system for the Northern Europe Computing Center, Kgs. Lyngby, Denmark. I wrote it in assembler language, (in those days, space and speed were priorities). It serviced the center's graphic activities for more than 10 years.
In 1973, I made one of the first computer-generated films. This involved jury-rigging a film camera in-place of the microfiche camera. The camera, a very-expensive piece of equipment was borrowed from Danmarks Radio (The national TV). At the Northern European University Computing Center, a simulation program by DHI (Danmarks Hydrauliske Institute) generated data that I converted into display commands to the CRT of the microfiche machine (20-odd 2400ft. tapes). During a whole weekend, I ran tapes and eventually ended with a 5 or 7 minute film, showing the simulation of a hurricane approaching Florida. The film was shown at a conference in the USA with great success.
In the early 1970's, I organized a computer graphics standards activity in Scandinavia and I was a founding member and part of the leadership of the IFIP Graphics Initiative. This group included experts from both East and West Europe and we organized and held three international seminars, with well known graphics experts from throughout the world (USA, Japan, Europe). Each seminar was edited published producing three well known scientific textbooks on computer graphics and interactive techniques. (publ. North Holland). The group also established the first international graphics standard GKS (Graphics Kernel System).
I was a founding member of the EuroGraphics Association and I served on the Board of Governors for many years. I was the Chairman of the Eurographics Conference in 1984.
