Curtain
The ribbon surface between an inner radius and a path: every point of the path, in order, is spanned radially from r_min out to its own radius along its own colatitude and longitude. Wire a spacecraft ephemeris into path for a curtain hanging below the trajectory, and Sample it through a field to color it. radial_res sets the number of quads between the inner radius and the path.

Parameter ports
Added from the Parameters pane (⊕). While connected, each drives its parameter.

|---|---|---|---|
r_min | primitive(number) | opt-in drives r_min | Drives the Inner radius parameter while connected |
radial_res | primitive(number) | opt-in drives radial_res | Drives the Radial resolution parameter while connected |
