2 Point Spline ============== .. image:: https://user-images.githubusercontent.com/14288520/188749135-04deebda-04b6-4a20-bad6-96eb96d4ecec.png :target: https://user-images.githubusercontent.com/14288520/188749135-04deebda-04b6-4a20-bad6-96eb96d4ecec.png 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 | | control 1 | Vector | the curve is mathematically attracted | +------------+--------+ | | 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.
