Demos

he applications here demonstrate some of World Wind’s rich capabilities. Also see World Wind Europa Challenge site for a collection of applications created by the World Wind Europa Challenge teams.

Requirements

Up to date video card drivers
Oracle Java Runtime Environment (JRE) 1.7.0
Java and OpenGL setup can be tested using JOGL demo site.

Application Template

This is the most basic usage of the SDK. It displays the default globe with its default layers. It includes capabilities such as a compass and status bar that are common to most applications, and presents Earth within a star field and with an atmosphere. It requires only 6 lines of code to instantiate everything seen here.

KML Viewer

Demonstrates loading, displaying, and interacting with KML content in World Wind.

WMS Layer Manager

This example application demonstrates the SDK WMS capabilities. It features a WMS layer panel that allows you to access any WMS server and layers.

To add a server, click on the + tab and enter a url. After the WMS discovery process, the list of available layers is displayed. Select one to add it to the current globe layer list. Unselect it to remove it.

Installing Images and Elevations

Installing Images And Elevations Demo

The World Wind Java Installing Imagery And Elevations Demo enables a user to install image data and elevation data from a file on the local hard drive. This data can be installed as a full pyramid of tiles or as a partial pyramid. Installing a full pyramid takes longer and consumes more space on the user’s hard drive, but has the best runtime performance. Installing a partial pyramid takes less time and consumes less space on the user’s hard drive, but requires that the original data not be moved or deleted.

Exporting Surface Imagery and Elevations

Demonstrates how to use the SectorSelector utility to save a selected region of surface imagery and elevations to a GeoTIFF file.

Scankort Denmark Data

Demonstrates high resolution imagery (0.2 meters per pixel) and elevation data (1.6 meters per pixel) served by the World Wind WMS, and visualized by the World Wind Java client.

Rigid Shapes

Demonstrates visualization of common rigid shape types in World Wind Java. Includes six rigid shape types: Box, Cone, Cylinder, Ellipsoid/Sphere, Pyramid, and Wedge.

Extruded Shapes

Shows visualization of textured 3D buildings with World Wind Java SDK Extruded Shapes.

Surface Shapes

Demonstrates visualization of common terrain following shapes in World Wind Java. Includes five surface shape types: SurfacePolyline, SurfaceQuad/SurfaceSquare, SurfaceEllipse/SurfaceCircle, SurfaceSector, and SurfacePolygon.

Airspaces

Demonstrates the World Wind Java controlled airspaces tookit.

Airspaces feature 3D volumes controlled by geographic coordinates and upper- and lower- altitude boundaries. Airspaces optionally conform to the terrain as you move them. They demonstrate what’s possible in terms of dynamic manipulation of data in 3D space.

Analytic Surface

Demonstrates visual representation of scalar values over a grid of geographic positions. AnalyticSurface supports dynamic scalar data by providing a simple, high throughput rendering pipeline for the application.

This demonstrates two unique surface types:

A dynamic surface representing random altitudes over the Coast of Florida, USA.
A static surface representing annual precipitation in Washington State, USA.

Video On Terrain

Illustrates how applications can display video on the globe’s surface.

Web Browser Balloons

Demonstrates use of World Wind browser balloons to display HTML, JavaScript, and Flash content to the user in the form of a screen-aligned balloon. There are two browser balloon types: ScreenBrowserBalloon which displays a balloon at a point on the screen, and GlobeBrowserBalloon which displays a balloon attached to a position on the Globe.

Annotations

This example allows you to experiment with the multiple options of World Wind Java annotation feature.

Annotations are text labels with support for multiline text, simple HTML and many styling attributes such as font face, size and colors, bubble shapes and background image.

On Screen Controls

Annotation Controls

Demonstrates the use of World Wind annotations to create simple user interfaces embedded into the World Window.

MGRS Graticule

Shows visualization of the Military Grid Reference System (MGRS) as a graticule overlayed on the globe’s surface.

Terrain Profiler

This application shows the terrain profile layer in action with its various controls. It allows you to view a realtime section profile graph for any place on the planet, at any scale - continent, country or mountain range… just by moving the mouse.

It proves particularly useful to explore the ocean floors where the bathymetry data reveals important geologic features.

Flat World Earthquakes

This example shows the latest earthquakes over a flat world projection. It allows you to see the whole globe at once while retaining the capability to zoom onto the surface and still experience 3D terrain.

Anaglyph Stereo

This is essentially the above application template but with anaglyph stereo viewing capability. It allows you to explore the world in ‘real’ 3D using red and cyan glasses with the red filter over the left eye.

To get a comfortable experience use the slider to adjust the interocular distance.

Multi-Window View Volume

Demonstrates World Wind Java SDK support for rendering globes in multiple application windows. World Wind automatically shares resources wherever possible across multiple windows in a single runtime environment.

View Tracking

Demonstrates how applications can keep a set of moving objects in view.

Line Builder

This simple example allows you to interactively draw a path over the terrain surface.

It demonstrates how an application can use and consume mouse events before they get to the default view input handler.

Airspace Builder

Demonstrates runtime construction of 3D shapes using the World Wind Java controlled airspace shapes.

New shape - Click the “New shape” button. When “Auto fill new shapes” is checked a default shape is created automatically
Select a shape - Left mouse button click
Delete a shape - Select the shape, then press the delete key.
Move a shape or move a control point - Drag the shape or control point with the left mouse button
Resize a shape - Hold the Shift key and drag any control point with the left mouse button
Create a control point - Hold the Alt key and click the left mouse button
Delete a control point - Hold the Ctrl key and click the left mouse button
