polyline-3d

schema/components/polyline-3d/1.0.1/polyline-3d.schema.json

The polyline-3d component describes a 3D polyline, defined as a contiguous sequence of vertices.

• begin — The starting index into the parent vertex array.
• count — The number of vertices in the polyline.
• closed — Whether the polyline forms a closed loop.

The referenced vertex coordinates follow the axis order declared in the object's coordinate_reference_system — see Coordinate reference systems and axis order.
