Schema
| Field | Type | Description |
|---|---|---|
type | LineType | Type of line primitive to draw. |
pose | Pose | The position and orientation of the line relative to the reference frame. |
thickness | float64 | Thickness of the line. |
scale_invariant | boolean | If true, thickness is fixed in screen pixels. If false, thickness scales with distance in world units. |
points | Point3[] | Points along the line |
color | Color | Single color applied to the entire line. Either this or colors must be provided. |
colors | Color[] | Per-point colors along the line. If specified, must match the number of points. Either this or color must be provided. |
