NURBS

One of the characteristics of a NURBS object is the knot vector. This is a sequence of numbers used to determine the influence of the control points on the curve. While you cannot edit the knot vectors directly, you can influence them through the Endpoint and Bézier options in the Active Spline panel. Note that, the Endpoint and Bézier settings only apply to open NURBS curves.

Tuần Hoàn U

See Common Options.

Bézier U

Makes the NURBS curve act like a Bézier curve. The NURBS control points act like Free handles of Bézier curve. Depending on the Order, 3 or 4 control points form one curve segment. Cyclic and Endpoint must be disabled for this option to work.

Điểm Kết Thúc U

Makes the curve contact the end control points. Cyclic must be disabled for this option to work.

../../../_images/modeling_curves_properties_active-spline_nurbs-endpoint.png — A NURBS curve with Endpoint enabled.

Bậc chiều U

The order of the NURBS curve determines the area of influence of the control points over the curve. Higher order values means that a single control point has a greater influence over a greater relative proportion of the curve. The valid range of Order values is 2-6 depending on the number of control points present in the curve.

../../../_images/modeling_curves_properties_active-spline_nurbs-order.png — NURBS curves with orders of 2.
