计算机图形学环境配置java3D
这个是默认到下图路径中：（记住这个路径，待会要导入jar包）
选择这个：
JDK18（或者一些版本都无法支持Applet类）
所以我把jdk改成了这个1.8版本就可以了：
idea配置
将java3D目录下面的bin目录中的dll文件拷贝到idea里配置的jdk路径的bin目录下：
idea里配置的jdk路径的bin目录：
把这个文件拷贝过去：
导入java3D的jar包
打开idea，选取环境，创建项目
右键External Libraries下的环境，打开库设置：
导入这个路径下的jar包：
C:\Program Files\Java\Java3D\1.5.1\lib\ext
步骤：
测试代码：

//对BranchGroupRoot预编译
