Horizontal cross-section actor, together with a transfer function.
The horizontal section actor draws a map of multiple forecast data fields at an arbitrary pressure altitude.
- The actor supports multiple forecast data fields.
- Each data field can be rendered as line contours, filled contours, pseudo-colour plot and textured stippling/hatching.
- The horizontal section can be interactively moved up and down by the user.
- Each horizontal section contains an instance of a graticule actor to render graticule lines and coast and border lines.
- A surface shadow is available to improve spatial perception.
- Multiple stacked horizontal sections are allowed in a single scene.
- Wind barbs and arrows are supported.
