# 2 Point Spline¶

## Functionality¶

Single section Bezier Spline. Creates a *Spline Curve* from 2 sets of points. Analogue to the Blender native Curve object, but limited to 2 pairs of *knots* and *control points* per curve.

## Inputs¶

Parameter | Type | Description |
---|---|---|

num verts | int | per curve this sets how many verts define the curve |

knot 1 | Vector | These place and adjust the shape of the curve. The knots are vectors on the curve, the controls are vectors to which the curve is mathematically attracted |

control 1 | Vector | |

control 2 | Vector | |

knot 2 | Vector |

The node accepts these The node will adjust to make sure the length of

## Parameters¶

The Node is vectorized in the following way. If any of the *knots* or *control points* are given in a list that doesn’t match the length of the other lists, then the last value of that shorter list is repeated to match the length of the longest.

This means; if *knot1, control1, knot2* are length 3, 4 and 8 and control2 is length 20 then
*knot1, control1, knot2* will all get their last value repeated till the full list matches 20 values.

The same *filling* procedure is applied to the *Num Verts* parameter.

## Outputs¶

- (verts, edges) : A set of each of these that correspond with a packet of commands like ‘knot1, ctrl1, ctrl2, knot2’
- verts needs to be connected to get output
- edges is optional

**optionals for visualizing the curve handles**

- hnd. Verts
- hnd. Edges

Passing hnd.Verts and hnd.Edges to a ViewerDraw node helps visualize the Handles that operate on your Spline curve.
