Grid Lines
A structured spherical grid of lines: for each of r, θ and φ, a range, the number of lines across it and the sample resolution along it, output as a polyline mesh. Equal range endpoints collapse that axis, so a single radius makes a longitude-latitude graticule, and a single colatitude and longitude make a polar axis; narrow ranges make a box around one location.
Inputs
None.
Parameter ports
Added from the Parameters pane (⊕). While connected, each drives its parameter.
| Port | Accepts | Mode | Description |
|---|---|---|---|
r | primitive(array) | opt-in drives r | Drives the r range parameter while connected |
r_lines | primitive(array) | opt-in drives r_lines | Drives the r lines parameter while connected |
t | primitive(array) | opt-in drives t | Drives the θ range parameter while connected |
t_lines | primitive(array) | opt-in drives t_lines | Drives the θ lines parameter while connected |
p | primitive(array) | opt-in drives p | Drives the φ range parameter while connected |
p_lines | primitive(array) | opt-in drives p_lines | Drives the φ lines parameter while connected |
Outputs
