![]() ![]() In the Installed Data window, locate the Create a full pyramid check box and select it if you are intending to use the imported data on the server, otherwise you can leave it unchecked. Here we use WorldWind’s LayerFactory to display the contents of a local OGC GeoPackage database. Once the Install Imagery And Elevations application is running, click on the Show Installed Data button to open the Installed Data window. ShapeAttributes attrs = new ShapeAttributes() ĪtInteriorColor(new Color(1, 1, 1, 0.5f)) // 50% transparent whiteĮllipse = new Ellipse(new Position(45, -100, 0), 500000, 300000, attrs) ģD Ellipse shapes are also possible: // Create an ellipse with the default attributes, an altitude of 200 km, and a 500km major-radius and a 300kmĮllipse = new Ellipse(new Position(25, -120, 200e3), 500000, 300000) ģD Ellipse shapes have additional configuration possibilities including extrusion and verticals: // Create an ellipse with custom attributes that make the interior 50% transparent and an extruded outline withĪtInteriorColor(new Color(1, 1, 1, 0. The GeoPackageFragment class extends BasicGlobeFragment and overrides the createWorldWindow method. ![]() The color of the interior, outline, and line widths can be customized using ShapeAttributes: // Create a surface ellipse with with custom attributes that make the interior 50% transparent and increase the RenderableLayer tutorialLayer = new RenderableLayer() A WorldWindow encapsulates an HTML canvas element. Almost all interactions between the app and Web WorldWind occur through a WorldWindow. The user can interact with the virtual globe by changing the view by moving, zooming, tilting, rotating. NASA World Wind is a virtual 3D globe open source development based on Java. It represents the presence of Web WorldWind in the web page. The rosworldwind package provides a simple GUI to display geo-referenced information on a virtual globe using the NASA World Wind technology. The Ellipse object is now fully configured and ready to be added to the WorldWindow for display on the globe: // Create a layer for the Sightline WorldWindow is the fundamental Web WorldWind object. ellipses are configured with a CLAMP_TO_GROUND altitudeMode and followTerrain set to true.Įllipse ellipse = new Ellipse(new Position(45, -120, 0), 500000, 300000) ĮtAltitudeMode(WorldWind.CLAMP_TO_GROUND) // clamp the ellipse's center position to the terrain surfaceĮtFollowTerrain(true) // cause the ellipse geometry to follow the terrain surface Several Ellipse objects are created, customized with ShapeAttributes, and then added to a RenderableLayer on the WorldWindow.Ĭreating a Surface Ellipse object: // Create a surface ellipse with the default attributes, a 500km major-radius and a 300km minor-radius. The EllipseFragment class extends the BasicGlobeFragment and overrides the createWorldWindow method. Configure your new project: You can use the default values. Select File > New > New Project to run the ne project wizard. ![]() ![]() This tutorial sets up a project from scratch and inserts a WorldWind globe in a FrameLayout. Describes the architecture of WorldWind Java. How to build a basic WorldWind Android ‘app’. The number of points used to build the outline is dynamic and based on the camera distance to the shape. Outlines some of the common issues users face and ways to resolve them. The outline of the ellipse is computed in geographic space using great circle distance. Here we position the Navigator’s camera at an aircraft’s location and point the camera at a nearby airport.This tutorial demonstrates how to configure an Ellipse shape and add it to the globe.Įllipse uses the provided major radius, minor radius, heading, and center position to draw an Ellipse on the globe. The CameraViewFragment class extends the BasicGlobeFragment and overrides the createWorldWindow method. Returns an RGBA color corresponding to the specified position from the original position list and its corresponding ordinal number by delegating the call to this paths positionColors. This example simulates a view from an aircraft above Oxnard, CA looking at the Point Mugu Naval Air Station.
