![]() 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. Tom Gaskins, NWW Technical Manager Rick Brownrigg, NWW Software Engineer ID#, TS-5523 Hi. World Wind is developed at NASA Ames Research Center by Chris Maxwell, Randy Kim, Tom Gaskins, Jessica Gan and project manager Patrick Hogan.1 NASA World Wind Java SDK 3D Earth in Your Applications and Web Pages The servers hosting this information are very busy and may be unresponsive until we get the necessary infrastructure. After a certain point, World Wind will begin to download more images automatically. World Wind comes with data you can zoom into. NET runtime environment and DirectX runtime. NET runtime environment and DirectX installed. Here is a list of video cards that have been reported to work with World Wind. If you don't know whether your machine comes with one, it is likely to have one built in if the computer was purchased within the past two years. World Wind benefits most from a video card with 3D acceleration. Intel Pentium 3, 1 GHz, or AMD Athlon or higher.Windows 2000, XP Home, or XP Professional.You may use it under the terms of the NASA Open Source Agreement. NASA World Wind is available as a full install, or as an update to a previous release. Look across the Andes, into the Grand Canyon, over the Alps, or along the African Sahara. Leveraging Landsat satellite imagery and Shuttle Radar Topography Mission data, World Wind lets you experience Earth terrain in visually rich 3D, just as if you were really there. World Wind lets you zoom from satellite altitude into any place on Earth.
