I was happily teaching physics at Bishop’s University (academic years 1996 and 1997 ) when fellow McGill graduates convinced me to join them in a physics simulation start-up company in Montreal. I ended up spending the next eight years building physics and collision detection software for all kinds of 3D environments, including robotic and vehicular simulators, video games running on PS2, XBox and GameCube, virtual actors, and 3D animation packages for the film industry.I still track these many forms of virtual reality through my involvement in Montreal ACM SIGGRAPH, a computer graphics organization that produces regular public events with invited speakers from industry and government, academic researchers, educators and artists exploring the digital domain.
