> No, I explained that nurbs require extra/different tools. I’m sorry if you feel defensive. I was responding to your explicit inclusion of “other curved surface representations” besides NURBS here https://news.ycombinator.com/item?id=23043791 https://news.ycombinator.com/item?id=23043791 and here https://news.ycombinator.com/item?id=23044537 https://news.ycombinator.com/item?id=23044537 Really just pointing out that a subdivision surface is literally another curved surface representation, does have some conceptual differences from polygons, and can be ray traced without subdivision. Calling it polygons was confusing to me, but now that I understand what you mean, call it polygons if you want.
