大家晚上好
啊 我是寻觅！
以后会有文章给大家介绍一个java 3D 游戏引擎现在，先委屈大家看个简单例子了，呵呵；
先给大家个游戏引擎下载地址大家可以先下去看看：在这里要感谢新朋友守护天使的推荐
http://www.mirrorservice.org/sites/download.sourceforge.net/pub/sourceforge/j/ji/jirr/
呵呵，废话少说了 开始解析代码
大家先要下载些东西，说实话java就是这样，功能不错就是麻烦
下载：
jmf-2_1_1e-windows-i586.exe
http://java.sun.com/products/java-media/jmf/2.1.1/download.html
Java 3D for Windows (32bit).exe
http://www.downloadjava3d.com/windows.php 或
https://java3d.dev.java.net/binary-builds.html
接着，安装就不说了，easy very
当然希望大家把doc也下来看看。
装好后，给大家一个经过我修改的简单实验代码：（由于时间关系，解说会放在以后）
