WorldWind Java - Community Edition (WWJ-CE)

WWJ-CE is community supported fork of the ubiquitous WorldWind Java SDK from NASA.

WorldWind Java is a 3D virtual globe API for desktop Java, developed by NASA. It provides a geographic context with high-resolution terrain, for visualizing geographic or geo-located information in 3D and 2D. Developers can customize the globe's terrain and imagery. The SDK provides a collection of shapes for displaying and interacting with geographic data and representing a range of geometric objects.

• WorldWindJava Wiki has setup instructions, developers guides and more
• API Documentation provides an extensive collection of useful JavaDocs for the WWJ-CE SDK
• WorldWind Forum provides help from the WorldWind community
• IntelliJ IDEA is used by the NASA WorldWind development team

Notice from NASA

On March 8, 2019, NASA announced a suspension of the WorldWind project.

WorldWind team would like to inform you that starting May 3, 2019, NASA WorldWind project will be suspended. All the WorldWind servers providing elevation and imagery will be unavailable. While you can still download the SDKs from GitHub, there will be no technical support. If you have questions and/or concerns, please feel free to email at:

[email protected]

WWJ-CE seeks to mitigate the effects of the suspension and continue the development of WorldWind Java.

Releases and Roadmap

Official WorldWind Java releases have the latest stable features, enhancements and bug fixes ready for production use.

• GitHub Releases documents official releases
• GitHub Milestones documents upcoming releases and the development roadmap
• Travis CI provides continuous integration and build automation

Run a Demo

The following options are available to run a WorldWind Java demo:

From the Apache NetBeans IDE

Clone the SDK with git, open the WorldWind Java project with Apache Netbeans and run demos via the Netbeans interface.

From a Windows Development Environment

• Download and extract the Latest Release
• Open the Command Prompt

cd [WorldWind release]
run-demo.bat

From a Linux or macOS Development Environment

• Download and extract the Latest Release
• Open the Terminal app

cd [WorldWind release]
sh run-demo.bash

Troubleshooting

WorldWind requires a modern graphics card with a current driver. Most display problems are caused by out-of-date graphics drivers. On Windows, visit your graphics card manufacturer's web site for the latest driver: NVIDIA, ATI or Intel. The drivers are typically under a link named Downloads or Support. If you're using a laptop, the latest drivers are found at the laptop manufacturer's web site.

JOGL Native Binaries

JOGL performs runtime extraction of native binaries. Some deployment situations may not allow this because it extracts the binaries to the application user’s temp directory. Runtime extraction can be avoided by by modifying WorldWind Java's JOGL distribution to load native binaries directly from the library path instead of dynamically using the native binary JAR files as follows:

1. Extract the GlueGen and JOGL native binary JAR files for the desired platform. These JAR files follow the naming pattern gluegen-rt-natives-PLATFORM.jar and jogl-all-natives-PLATFORM.jar
2. Place the extracted native binaries either in the program's working directory or in a location specified as the library path. The following JOGL user's guide page outlines supported library path variables: https://jogamp.org/jogl/doc/userguide/index.html#traditionallibraryloading
3. Remove the GlueGen and JOGL native binary JAR files from your application's workspace. JOGL attempts to use the native binary JAR files before loading from the library path, so these files must not be deployed with the application.
4. When running, specify the JVM argument -Djogamp.gluegen.UseTempJarCache=false

GDAL

GDAL is a translator library for raster and vector geospatial data formats provided by the Open Source Geospatial Foundation. GDAL libraries and native binaries are not provided by WorldWindEarth/WorldWind Java, but are needed to build. The Gradle build will pull the necessary libraries from Maven. Please see the file GDAL_README.txt for details on where to obtain the native binaries and other details.
