Wednesday 4th of January, the staff at the department (IDI) gathered to celebrate Torbjørn Hallgren's 70 years birthday. Hallgren is signing off after 44 years at the university and SINTEF, but he still wish to contribute with graphic research at the department through his colleagues.
After graduating in 1966 from the Technical Physics programme of study at Norwegian Institute of Technology (NTH), Hallgren started working at Regnesenteret (RNTH). At RNTH he worked with technical/mathematical programming and taught the SIMULA programming language. Later he joined the Academic Administration at NTH, and pioneered the development of software for their academic needs.
In 1986 Hallgren joined our department, and started lecturing the major subjects in programming. His main responsibility has been computer graphics.
Hallgren was one of the initiators of the Distributed Visualization Laboratory (DVL). DVL began as a collaboration between departments and faculties at the university, since computer graphics and visualization required expensive equipment. Hallgren was crucial in establishing the cooperation - he has been a pioneer for computer graphics and visualization at the university.
