The knot-vector in U direction is a list of sizem=+n-1 knots where p is the polynomial basis degree and n is the number of control points. The knot vector consist of a non-decreasing sequence of values. Knot multiplicities can be included. A knot multiplicity means that a knot value can be repeated up to p+1 times. UknotVector has the following attributes:
| Attribute | Namespace | Type | Use | Default | Fixed | Description |
|---|---|---|---|---|---|---|
| value | ocx | ocx:doubleListType | req. | The list of knots separated by white space. Knots must pe provided in increasing order. |
