java3D安装

开发环境：

win8 64 +jdk8

教程地址：http://www.java3d.org/tutorial.html

步骤：

1. jdk安装部署——略

2. 安装java3D

https://java3d.java.net/binary-builds.html

笔记本是64位，因此下载j3d-1_5_2-windows-amd64。注意，j3d-1_5_2-windows-i586.zip和j3d-1_5_2-windows-amd64不是指对应的cpu，有效的是最后2位数字。被这个坑了一阵子……

解压后发现两个文件夹，bin和lib

老规矩，lib包里的jar导入到项目classpath

bin的处理新鲜一点，我把它copy到src下，而后，

好了，环境部署到此结束。接下来run你本身的代码就好。比方说：

import com.sun.j3d.utils.universe.*;
import com.sun.j3d.utils.geometry.ColorCube;
import javax.media.j3d.*;
import javax.vecmath.*;
import java.awt.GraphicsConfiguration;

/**
 * Simple Java 3D example program to display a spinning cube.
 */
public class HelloUniverse extends javax.swing.JFrame {

    private SimpleUniverse univ = null;
    private BranchGroup scene = null;

    public BranchGroup createSceneGraph() {
 // Create the root of the branch graph
 BranchGroup objRoot = new BranchGroup();

 // Create the TransformGroup node and initialize it to the
 // identity. Enable the TRANSFORM_WRITE capability so that
 // our behavior code can modify it at run time. Add it to
 // the root of the subgraph.
 TransformGroup objTrans = new TransformGroup();
 objTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
 objRoot.addChild(objTrans);

 // Create a simple Shape3D node; add it to the scene graph.
 objTrans.addChild(new ColorCube(0.4));

 // Create a new Behavior object that will perform the
 // desired operation on the specified transform and add
 // it into the scene graph.
 Transform3D yAxis = new Transform3D();
 Alpha rotationAlpha = new Alpha(-1, 4000);

 RotationInterpolator rotator =
     new RotationInterpolator(rotationAlpha, objTrans, yAxis,
         0.0f, (float) Math.PI*2.0f);
 BoundingSphere bounds =
     new BoundingSphere(new Point3d(0.0,0.0,0.0), 100.0);
 rotator.setSchedulingBounds(bounds);
 objRoot.addChild(rotator);

        // Have Java 3D perform optimizations on this scene graph.
        objRoot.compile();

 return objRoot;
    }

    private Canvas3D createUniverse() {
 // Get the preferred graphics configuration for the default screen
 GraphicsConfiguration config =
     SimpleUniverse.getPreferredConfiguration();

 // Create a Canvas3D using the preferred configuration
 Canvas3D c = new Canvas3D(config);

 // Create simple universe with view branch
 univ = new SimpleUniverse(c);

 // This will move the ViewPlatform back a bit so the
 // objects in the scene can be viewed.
 univ.getViewingPlatform().setNominalViewingTransform();

 // Ensure at least 5 msec per frame (i.e., < 200Hz)
 univ.getViewer().getView().setMinimumFrameCycleTime(5);

 return c;
    }

    /**
     * Creates new form HelloUniverse
     */
    public HelloUniverse() {
 // Initialize the GUI components
 initComponents();

 // Create Canvas3D and SimpleUniverse; add canvas to drawing panel
 Canvas3D c = createUniverse();
 drawingPanel.add(c, java.awt.BorderLayout.CENTER);

 // Create the content branch and add it to the universe
 scene = createSceneGraph();
 univ.addBranchGraph(scene);
    }

    // ----------------------------------------------------------------
    
    /** This method is called from within the constructor to

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        setTitle("HelloUniverse");
        drawingPanel.setLayout(new java.awt.BorderLayout());

        drawingPanel.setPreferredSize(new java.awt.Dimension(250, 250));
        getContentPane().add(drawingPanel, java.awt.BorderLayout.CENTER);

        pack();
    }// </editor-fold>//GEN-END:initComponents
    
    /**

    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new HelloUniverse().setVisible(true);
            }
        });

}

java3d的下载命名和本地库的设置着实坑了我一阵。

还有两个问题，一是不开放源码，看代码注释很不方便；二是java3d已经暂停维护了？！真的太糟糕了。

并且，堂堂java程序，除了JVM，竟然还要本地库的支持？？

啧啧，吃枣药丸啊——
