vJSONTorus
Generate points on a torus from a major radius, a minor radius and segment counts around the ring and the tube.
vJSONTorus has no input and outputs an array of XYZ points on a torus that lies in the XY plane around the Z axis. U Segments and V Segments set the point count, and U Sweep limits how much of the ring is generated.
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| Major Radius | Float | 0.35 | Distance from the center of the torus to the center of the tube. Minimum 0.001, default 0.35. |
| Minor Radius | Float | 0.1 | Radius of the tube. Minimum 0.001, default 0.1. |
| U Segments | Integer | 24 | Number of positions around the ring. Clamped to 3 or more, default 24. |
| V Segments | Integer | 12 | Number of points around the tube at each ring position. Clamped to 3 or more, default 12. |
| U Sweep | Float | 360 | Angle covered around the ring, in degrees. Range 0 to 360, default 360. |

The node places V Segments points around the tube at each of U Segments positions around the ring, so the output holds U Segments * V Segments points, ordered ring position by ring position. For ring angle u and tube angle v, X = (Major Radius + Minor Radius * cos v) * cos u, Y = (Major Radius + Minor Radius * cos v) * sin u and Z = Minor Radius * sin v.
With the defaults (Major Radius 0.35, Minor Radius 0.1, 24 U Segments, 12 V Segments, U Sweep 360) the node outputs 288 points forming a closed torus centered on the origin. The tube angles always cover a full circle.
U Sweep sets the angle covered around the ring, from 0 to 360 degrees. Include End decides where the last ring position lands. With it off, the sweep is divided by U Segments, so a 360 degree sweep stops one step short of the start and no ring is repeated. With it on, the sweep is divided by U Segments - 1, the last ring lands on the end of the sweep, and a 360 degree sweep puts the last ring on top of the first.
Both segment counts are clamped to 3 or more. The node does not compare the two radii, so a Minor Radius larger than the Major Radius gives a self-intersecting surface. The output contains points only, with no edges or faces.
