Class AirspaceBuilder

java.lang.Object

gov.nasa.worldwindx.examples.ApplicationTemplate

gov.nasa.worldwindx.examples.AirspaceBuilder

public class AirspaceBuilder
extends ApplicationTemplate

Illustrates runtime construction of 3D extruded polygons and spheres using World Wind Airspace shapes. This uses a PolygonEditor and a SphereAirspaceEditor to enable runtime editing of Polygon airspace and SphereAirspace shapes.

Usage Instructions

Adding and Removing Shapes
Add a shape by selecting either Polygon or Sphere in the drop down box then clicking New shape. Delete a shape by left-clicking it then pressing the delete key.

Moving Shapes
Move a shape by left-clicking and dragging it.

Editing Spheres
Note: a sphere must be selected before it can be edited. Select a sphere by left-clicking it.
Adjust a sphere's height by holding the Shift key then left-click and drag the sphere. Resize a sphere by moving the cursor toward the sphere's edge until a blue control point appears, then left-click and drag the control point.

Editing Polygons
Note: a polygon must be selected before it can be edited. Select a polygon by left-clicking it.
Add a polygon vertex by holding the Alt key and left-clicking anywhere near the polygon. Remove a polygon control point by holding the Control key and left-clicking the blue sphere at the vertex. Move a polygon vertex by left-clicking and dragging it. Change a polygon's bottom or top height by holding the Shift key then left-click any blue sphere at a vertex and drag it.

Demo Shapes

Select File -> Load Demo Shapes to display a set of polygon airspace shapes built with this editor. The data for these shapes is located in the World Wind project under src/gov/nasa/worldwindx/examples/data/AirspaceBuilder-DemoShapes.zip.
