WorldWind Java

New version of WorldWind Java released

WorldWind Java 2.2.1 is now available on GitHub. This version of WorldWind Java is a maintenance release that addresses small fixes (typos, bad references, etc.) to various areas of the code and removes references to services that are no longer supported by the WorldWind servers.

WorldWind's API remains unchanged in this release and we are committed to maintaining a consistent API in future releases. More information on the release can be found at this link: WorldWind Java 2.2.1.

Please direct questions to our new email address: [email protected].

3D virtual globe API for desktop Java, developed by NASA. 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. Provides a collection of shapes for displaying and interacting with geographic data and representing a range of geometric objects.

• worldwind.arc.nasa.gov has setup instructions, developers guides, API documentation and more
• Apache NetBeans is used by the NASA WorldWind development team

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 Most display problems are caused by out-of-date graphics drivers.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
