首先从google 官方搞到一个SDK,他有flex和flash两个版本的swc，分别考入flash的文件夹内。注意flashcs3和flashcs4的文件夹是不一样的。然后按ctrl+f7，组件列表里面就会出现googlemap的图标，把它拖动到舞台上，然后删除掉，这样它就在你的library里面啦。好，首先我们先try一下直接的应用。

再来看一下如何应用到papervision中，googlemap不能直接作为材质进行渲染，所以有高人想到了用bitmap.draw的办法，转换为bitmap，再贴到各种形状上，当然，这样的googlemap是不能进行互动的，比如不能缩放，不能拖动。在flash cs4里面，用flash cs4自带的3d api能直接操作google map，这个以后会讨论到. 由于flash的bitmap.draw()有security的限制(adobe的说法是防止远程拷贝机密的档案照片等)。所以在这边无法显示，除非googlemap公布crossdomian的用法。
