本文介绍如何搭建Java3D开发环境，并提供了一个简单的3D矩形演示示例。包括下载安装Java3D、配置Eclipse以及运行示例代码的步骤。

1.下载java3d安装包，默认安装即可。
2.打开eclipse，新建java3d项目。
3.“Project -> Properties -> Libraries -> add external jars”导入安装包内的jar文件，一共3个。

下载3d的jdk地址：http://www.oracle.com/technetwork/java/javase/tech/index-jsp-138252.html

测试环境是否搭建好的代码：

import java.applet.Applet;
import java.awt.BorderLayout;
import com.sun.j3d.utils.applet.MainFrame;
import com.sun.j3d.utils.geometry.*;
import com.sun.j3d.utils.universe.*;
import javax.media.j3d.*;
import javax.vecmath.*;
import com.sun.j3d.utils.behaviors.mouse.MouseRotate;
import com.sun.j3d.utils.behaviors.mouse.MouseZoom;
import com.sun.j3d.utils.behaviors.mouse.MouseTranslate;

public class Rectangle extends Applet
{
private SimpleUniverse universe ;

public Rectangle()
{}

public void init()
{
  //canvas to draw on, ask SimpleUniverse what config to use
  Canvas3D canvas = new Canvas3D(SimpleUniverse.getPreferredConfiguration());
  setLayout(new BorderLayout());
  add("Center", canvas);

//create top of our scene graph
BranchGroup scene = new BranchGroup();

  //create universe, and attach our geometry to it.
  SimpleUniverse u = new SimpleUniverse(canvas);
  u.getViewingPlatform().setNominalViewingTransform();

// Create the bounding leaf node
BoundingSphere bounds = new BoundingSphere(new Point3d(0.0,0.0,0.0), 100.0);

  // Create the transform node
  TransformGroup transformGroup = new TransformGroup();
  transformGroup.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
  transformGroup.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);

  // Create the drag behavior node
  MouseRotate behavior = new MouseRotate();
  behavior.setTransformGroup(transformGroup);
  transformGroup.addChild(behavior);
  behavior.setSchedulingBounds(bounds);

  // Create the zoom behavior node
  MouseZoom behavior2 = new MouseZoom();
  behavior2.setTransformGroup(transformGroup);
  transformGroup.addChild(behavior2);
  behavior2.setSchedulingBounds(bounds);

  // Create the zoom behavior node
  MouseTranslate behavior3 = new MouseTranslate();
  behavior3.setTransformGroup(transformGroup);
  transformGroup.addChild(behavior3);
  behavior3.setSchedulingBounds(bounds);

  transformGroup.addChild(new ColorCube(0.4));

  scene.addChild(transformGroup);
  u.addBranchGraph(scene);
}


// The following allows UglyCube to be run as an application
// as well as an applet
public static void main(String[] args)
{
  new MainFrame(new Rectangle(), 256, 256);
}
}
