Notes

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.

但我發現我改的FireGL T2有些會有破圖、殘影現象，不知道是卡的關係還是NASA伺服器的關係

較著名的地方能用以較低位置看的清楚
不知道該如何設才比較看的更精細
聽說有人能用200公尺高空觀看
但我頂多只能用20多公里來觀看
就待大家來研究
但台灣仍是看不清楚，殘念



以下是東京（139.79929E，35.71291N）25公里高空拍攝
和俯視整個東京灣
