   World Wind benefits most from a video card with 3D acceleration. 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. Here is a list of video cards that have been reported to work with World Wind.

     World Wind requires that you have .NET runtime environment and DirectX installed. You can download .NET runtime environment and DirectX runtime.

     World Wind comes with data you can zoom into. After a certain point, World Wind will begin to download more images automatically. The servers hosting this information are very busy and may be unresponsive until we get the necessary infrastructure.

     NASA World Wind leverages Microsoft .NET technology for rapid development and to easily access open standards such as XML, WMS, and other graphics standards. Real-time 3D graphics are driven by DirectX allowing a wide base of compatibility with accelerated video hardware.

     Primary data sources come from NASA, and TerraServer-USA of Microsoft Research.
