Single-Point Curve

Functionality

This node generates a trivial curve, which consists of only one point in 3D space. Such a curve is not useful by itself, but it can be useful in combination with nodes which use curves to make some more complex construction. For example, it is possible to do a loft with a single-point curve.

• Vector-> Vector In

• Text-> Stethoscope

• Viz-> Viewer Draw Curve

Inputs

This node has the following input:

• Point. The point which will become the Curve object. The default value is (0, 0, 0).

Parameters

This node does not have parameters.

Outputs

This node has the following output:

• Curve. The generated Curve object.

Examples of Usage

Use with “Blend Curves” node to construct a smooth continuation of given curve, which ends in a specific point:

• Curves-> Blend Curves

• Viz-> Viewer Draw Curve

• Scene-> Bezier Input

Use with “NURBS Loft” node, to construct a surface which has “poles”:

• Curves-> Bezier Spline Segment (Curve)

• Surfaces-> NURBS Loft

• List->List Main-> List Join

• Viz-> Viewer Draw Surface
