Yes, this (Lyle Ramshaw&#x27;s paper). My impression is that his work succeeds in finding the simplest human-comprehensible way of defining these objects. It&#x27;s very much not the pragmatic &quot;local hacker&quot; approach to graphics, which can be forbidding.<p>I also enjoyed this interview with Tony DeRose:

I think there&#x27;s probably more scope to humanize it, as Ramshaw and DeRose&#x27;s demonstrations suggest.
