Creation method

There are two options for creating a NURBS Curve node.

  • The first way to create a NURBS Curve node is using the search list, which is opened by double left-clicking in the workspace. You can write the name of the node you need or words associated with this node.
    • Non-uniform , rational , B-spline , crv
  • The second way is to select a NURBS Curve node from the menu that opens from the top left.
    • Menu > Tool > Primitive Curves > NURBS Curve

Steps

  • Create a NURBS Curve node.
  • Connect a boolean value to the first port that shows the open or close curve.
  • Connect the degree of the curve to the second port.
  • Connect an array of points or a point to the third port, this port has the function of adding ports to which you can connect other points.

Connect a boolean value to the first port that shows the open or close curve. Connect the degree of the curve to the second port. Connect an array of points or a point to the third port, this port has the function of adding ports to which you can connect other points. On the output port, you will receive the resulting NURBS curve.
