I’m probably preaching to the choir here, but in case you haven’t already heard, there are two new videos on PGA worth checking out:

  1. Leo Dorst’s intro to PGA at CGI2020: “PGA: Plane-based Geometric Algebra: a complete framework for euclidean geometry”. Clear overview over the whole subject in just 35 minutes!
  2. Steven De Keninck’s GAME2020 talk “Demystifying Dual Quaternions”. A fascinating treatment building up PGA out of the euclidean motions, beginning with the reflections, and adding the geometry later. A lot of cool ideas packed into 48 minutes!
