WebNov 9, 2013 · Periodic knot vectors do not repeat the start and end numbers (that's the whole point of periodic). Nurbs surface vectors are basically the same, except you need 2 of them (one for u, one for v). The numbers in the parenthesis refer to the domain of the surface. The U domain of your surface is from 0.06 to 0.95 and V goes from 0.50 to 1.00 WebThe above explanation shows that the knot vector is very important. The knot vector can, by its definition, be any sequence of numbers provided that each one is greater than or equal to the preceding one. Some types of knot vector are more useful than others. Knot vectors are generally placed into one of three categories: uniform, open uniform ... iot livestock monitoring
