Java3D安装(idea版)

点击此处，获取更良好的阅读体验

前言

正值学习计算机图形学期间，学校选用的是比较冷门的Java3D，网上的安装教程也比较少，安装教程仅供参考。

1. JDK安装

JDK 点击下载
可以下载1.8或11稳定版本，这里记得要在我的电脑中配置环境，由于教程众多这里不再赘述

2. Java 3D 1.5.1

Java3d 点击下载
根据自己的系统选取，例如本人用的是windows，则选java3d-1-5-1-windows-i586.exe（代表32位）

这里注意一点，JDK和Java3D的位数需相同，例如JDK用的32位，Java3D库也需32位

3. idea的安装

idea 点击下载
下载community版本即可，如有激活码或其它途径可下载ultimate版本

以上三样安装安装好之后，即可打开idea进行配置

---

• ddl文件配置
  将Java3D bin目录文件下的ddl文件拷贝至JDK bin目录下，否则将报异常UnsatisfiedLinkError

• 打开idea，选取环境，创建项目
  右键External Libraries下的环境，打开库设置

• 添加jar包

• 找到java3d的安装位置，默认是在以下路径
  \Java3D\1.5.1\lib\ext
  将jar包导入即可
  （64版本的Java安装路径可能无(x86)）

• 最后用代码测试结果
