  1. 11:07 I think the mathematical term for this is “gimbal lock”. It’s a well-known hazard of working with Euler angles. Hmmm ... could you use quaternions as an angular coordinate system instead?

  2. 1:52 Ha! You called it “gravitational lensing”!

  3. You do know it’s the R³ part I’m talking about, right?

  4.  @Eltaurus  You yourself wrote it as a Cartesian product. That means the P and R³ are separable. Do you know what that means?

  5. Presumably the problem was simplified a bit, over conventional CG ray-tracers, in that you didn’t have to deal with any actual bounces off objects. You just followed each ray from the camera until it hit an object (or exceeded some maximum range), and left it at that. No issues with diffuse versus specular materials, lighting etc.

  6. By the way, arxiv.org seems to block certain user agent strings. I had to use “--user-agent="Not firefox"” with wget to retrieve the paper.
