ASK HN COMMENT: Can anyone here point to / have anything to add on the mathematics of defining curved surfaces with greater than 4 edges?
Most software requires you to define patches with 3 or 4 edges, in some cases the natural curves you would want to model create areas of 5 or more sides.
- atoav 5y agoI have been NURBS modelling professionally for a while, the way >4 sided curved surfaces are usually done is by bulding a <=4 sided surface and then intersecting it with another surface to trim a corners away. So techically most 5, 6 etc sided NURBS surfaces you see in the wild are just 4 sided surfaces with part of the surface hidden.
