Avalon 与 3D。

    很早之前就知道avalon有3D支持,尤其那个球的Demo,http://blogs.msdn.com/danlehen/archive/2004/06/01/146259.aspx,前几天刚刚下到CTP,Win FX SDK中的3D例子很少,而且不怎么好用,就目前对xaml的认识还不足以改正其中的错误,无奈,只好再寻例子了,上周末找了半天,终于找到了,在一个录像中照扒下来的。

运行效果如图,视角是移动的。


    这又不禁让我想起了VRML,2年前,我学VRML的时候,就曾经想过,其实VRML应该用XML来写,结果Xaml真的出现了,更出乎意料的是,是MS搞的,那些致力于WEB 3D的公司为什么没有自己把VRML形成XML系列的标准呢,唉,给MS抢了先了。
