A Bigger Mathematical Picture for Computer Graphics
Slideshow & audio of Eric Lengyel’s keynote in the 2012 WSCG conference in Plzeň, Czechia, on geometric algebra for computer graphics. Short abstract: "This talk introduces the basic concepts of the exterior algebra (aka geometric algebra or Clifford algebra) and presents a bigger mathematical picture that enables a deeper understanding of computer graphics concepts such as homogeneous coordinates for representing points, lines, and planes, the operations that can be performed among them using the progressive and regressive products, and incomplete pieces of the bigger picture, such as Plücker coordinates."
