Alain Fournier (1943–2000) was a computer graphics researcher and professor at the University of British Columbia.
In 1980 he received a Ph.D. in computer science from the University of Texas at Dallas under the supervision of Zvi Meir Kedem, and with Donald Fussell and Loren Carpenter reported the results of his Ph.D. work on stochastic modelling in a seminal paper in 1980.
Fournier made contributions to computer graphics dealing with modelling of natural phenomena.
He once called his approach impressionistic graphics and it both revolutionized the field and drove it forward.
His subsequent work dealt with illumination models, light transport, rendering, and sampling and filtering.
