PVANodes ▸ Datasets ▸ Point Generation
Fibonacci Sphere
Generates an evenly spread lattice of points on a sphere around each point of the optional x input (shown once connected or pinned), or around center alone. It is handy for field-line launch points.
Inputs
| Port | Accepts | Required | Description |
|---|---|---|---|
x | dataset | optional, quiet: shown when relevant, connected or pinned | Points to generate around; unwired, the center parameter is the single seed |
Parameter ports
Added from the Parameters pane (⊕). While connected, each drives its parameter.
| Port | Accepts | Mode | Description |
|---|---|---|---|
center | primitive(array) | opt-in drives center | Drives the Center parameter while connected |
n | primitive(number) | opt-in drives n | Drives the Points per Sphere (n) parameter while connected |
radius | primitive(number) | opt-in drives radius | Drives the Sphere Radius parameter while connected |
Outputs
