A Geometrical Puppetshow: Real-time Interactive Computer Animation

George Francis, U. Illinois

Watching a toy gravitational lens distort our world is just one of many ways of using computer graphics to simulate impossible phenomena, and so convey mathematical ideas rather than create photo-realistic images of real events. This demonstration includes videos, computer demonstrations, and even some words on meta-realistic rendering of 4-dimensional and non-Euclidean geometry.
