Properties
Name Type Cardinality AppliedStereotypes Description
order unsignedInt 1..1 XSDattribute Order of the NURBS trajectory. This is the order of the curve, not the degree of the polynomials, which will be one less than the order of the curve. Range [2..inf[.
controlPoints ControlPoint 2..* XSDunwrapped Control point vector of the NURBS trajectory. The number of control points must be greater or equal to the order of the curve.
knots Knot 2..* XSDunwrapped Knot vector of the NURBS trajectory. Knot values must be given in ascending order. The number of knot vector values must be equal to the number of control points plus the order of the curve.
