Here you see WWJ as a component in an Eclipse Rich Client Platform application. A particular consideration was being able to fit into application frameworks. Not something that WWJ provides.ĩ Eclipse RCP Early on we decided that we’d be as platform neutral as possible. This is the app’s own imagery, by the way. I don’t know what this application is doing, but it certainly looks serious. People are doing serious stuff with WWJ and expect a professional product. The rest is implemented by the application.Ĩ High Precision It’s not just pretty pictures either. In all these applications It’s just a slave, a supporter of the application’s real mission. Single Frameħ WWJ Is Only a Piece If there is one thing I want you to take away from this session, it’s that WWJ is a component. Notice the cute coordinate selector on the status bar. At bottom left is a command and controll applications that manages worldwide sensors It uses a single frame. In the upper right is a program that animates time-series data visualization. You can use WWJ in just about any configuration you want. They include appliclations for Simulation Analysis Organization Fun Most of them could not be done without WWJ There are many more WWJ applications than these, some we know about and some we know we’re not supposed to know about. Point to each and say what it isĪll these applications are using WWJ. What kind of applications? … next slide…ĥ Find World Wind Java These kinds. It’s intended to be a piece of many applications. It takes care of the hard problems: - Terrain generation - Surface imagery - Getting the right information from the server when it’s needed - All the tricks necessary to make all this happen very quickly - Viewing and selection - The data and the servers to provide it And you get all this in a component as simple to plug in as a Jbutton. WWJ provides applications with an interactive 3D Earth context. Instead of plugging your logic into someone else’s program, you plug the world into your own application. We decided to flip things around, and create WWJ plug-in. The original NASA World Wind provided a plug-in capability, which helped a lot, but it is still someone else’s application. That’s very constraining and tremendously limits their usefulness. Solves the Geo-browser problem Makes app the master instead of a servant WWJ is a Component A plug-in providing an Earth context for applications Does the hard stuff Terrain generation from real, remote data at high frequency Image display and selection from terabytes of remote imagery Rapid management of data retrieval from distributed sources Getting it all to show up when and where it’s supposed to In a component as simple to use as a Jbutton Viewing and picking Cross-platform and Open-source WWJ Is Not an Application Earth browsing is mostly done today in a few well-known stand-alone applications, in particular, GE and MS Virtual Earth. Show how to deploy it with Java Web Start or in a web browser. Show how to build a WWJ application and a WWJ applet. Describe the architecture, which is something you need to understand to use WWJ, but is simple. Will show some examples that would be hard to do without WWJ. WWJ’s Features and purpose WWJ’s Architecture Build a WWJ Application Deploy a WWJ Applet Where to get WWJ and help There’s a difference between WWJ and the current crop of Earth browsers. To show you to put 3D Earth into your own applications What World Wind is currently capable of Agenda on next slideģ Agenda What WWJ is and is not Unique WWJ Examples Ask for show of hands of those who: Have used or are using WWJ Know more about WWJ then what is in the program Are here because they couldn’t get into the session they really wantedĢ Learn how NASA World Wind makes building 3D-Earth applications easy and flexible. Tom is Technical Manager of the NASA World Wind Project Rick is senior engineer, responsible or server-side software currently. Thanks for coming to hear about NASA World Wind.
