What is NASA World Wind Java?

NASA World Wind Java is an SDK aimed at developers who want to create their own virtual globe applications.

General questions

Why are the World Wind Java demos missing features of World Wind 1.4?

NASA World Wind Java is an SDK. It is meant for developers and not end users. The bundled application and webstart on the NASA Java page are just simple demos to show how to get started with the SDK.

Will World Wind Java run on my operating system?

The NASA World Wind Java SDK is platform independent. The demo has succesfully been run under Ubuntu, Microsoft Windows, Mac OS X and Fedora Core 6. However, your computer still must have a modern graphics card with an up-to-date driver.

Why do I get a blank screen?

A blank screen is typically caused by out of date graphics drivers. Please update them from the graphics card manufacturer.

Will there ever be a World Wind Java client?

The goal is 100s of World Winds, not one. That's why NASA created WWJ as a Java component. NASA has no plans to create a World Wind Java client similar to World Wind .Net. They plan only to continue to develop and expand the SDK.

Development specific questions

What is the status of the SDK? Is it a pre-alpha, an alpha, a beta or a release... or something else? Is it safe to start coding an application around it ?

The WWJ release as of May 11, 2007 is an early-access release. The code and the API will continue to evolve, although the architecture will remain the same. When a stable release is established, the APIs will follow the convention of backwards compatibility among "dot" releases. No date for a stable release has been established yet. The components of WWJ are designed to be replaceable. The architecture is largely defined by pure interfaces. To replace a component, just implement the relevant interface(s).
