![]() ![]() 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. Sun shading and Atmospheric scattering thread on WWC forum.1 NASA World Wind Java SDK 3D Earth in Your Applications and Web Pages.In addition, the ligth options dialog now let you change the light and shadows colors for special effects like sunsets or full moon. Dragging the mouse with the middle button down will change the sun heading (horizontal) and elevation (vertical). The mouse middle button when clicked turns the light on and off - with a 'light switch' kind of noise. More light controls have been added into WW 1.4.1. During 1.4 beta testing, i spent quite some time ironing out shading and atmospheric scattering issues and added the much needed 'manual control' to set the light orientation at will. It is definitly something you want for a non shaded topo or geology map.Ĭhris Maxwell added the basic code into WW 1.4 but didnt have the time to finish up the integration before being assigned to the Java team. Some think of it as a little gadget, but in fact it is a very usefull tool that can dramatically enhance existing layersets by bringing out more terrain details and also providing a more 'natural' rendering of the overall scenery. One of the really nice features of WW 1.4 is the light. * Shadow over the rings should not affect stars seen through the rings or main body ![]() * If ring texture does not end with a clean transparent border, ring projection on main body is dirty on the bottom edge * Some wild polygons in the shadow over the rings - RingShadow(), depending on sun orientation ![]() 0.1a1Ěpr 25, 2006ğirst light - very alpha: ZBuffer issue / Stencil ? 0.1 Apr 25, 2006Ědded ZBuffer occlusion with a 'virtual sphere' 0.2 Apr 26, 2006Ĝamera tilt and proximity bug solved + better texture for Saturn 0.3 Settings per world and testing shadows. 0.5 Removed moire and Zbuffer cleared after rendering (for grid lines) 0.7 May 17, 2006Ědded rings projected shadows on main body and fixed/not fixed sun settings 0.7b May 17, 2006ğixed ring shadow on main body opacity 0.8 Use inverted texture for projection and 'unlit' rings side 0.8b May 18, 2006ğixed shadow on rings that was 'floating' above the ring plane. 0.9 May 20, 2006Ědded atmospheric winter glow and all effects as settings options ![]()
