Is there documentation covering the interesting material in the “New Hope” videos from Brazil 2021?
On bivector.net, the basics of PGA are covered in various write-ups, like PGA4CS. We (Steven De Keninck and Leo Dorst) are finishing up two new ones, an easier/shorter version of that, and a tutorial on classical mechanics in PGA - basically done apart from some demos.
The bit I was keen to understand better was that reflection sometime reverses the orientation and sometimes preserves it, depending on how the “object” being reflected was created. At least that was the impression I got. I should rewatch it.
Can someone post the link to the videos?
