vJSONPointsOnArc
Builds an arc of points between each pair of consecutive input points.
vJSONPointsOnArc takes an array of points and outputs Smoothness + 1 points on an arc between each consecutive pair. With the default Height Factor of 0 each arc is a half circle in the XY plane with the two points as its diameter.
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| Smoothness | Float | 20 | Number of segments per arc. Range 1 to 100, default 20. |
| Height Factor | Float | 0.0 | Hidden control. Bends the arc sideways and lifts it on Z. Slider 0.001 to 1, default 0. |
| Multiplier | Float | 0.0 | Hidden control. Multiplier. Read by the code but not used. Default 0. |
| Input | DATATYPE | — | Points that the arcs connect, in order. Each needs 3 values. |
Read the full description
For every pair of neighboring input points the node places Smoothness - 1 points between them and keeps the two input points at the ends. Each point is the start point turned around a center by an angle that runs from 0 to 180 degrees. With Height Factor 0 the center is the middle of the pair, so the arc is a half circle in the XY plane, and Z follows a cosine between the two Z values.
Height Factor (hidden, default 0) moves the center sideways by half the distance times the factor and lifts the middle of the arc on Z by the factor times the distance. Smoothness runs from 1 to 100 with a default of 20. A point shared by two pairs is written twice. Fewer than 2 input points give an empty output.
