New PGA videos from Leo Dorst and Steven De Deninck

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!
