simbad基本用法-1

下载simbad,然后需要安装jdk和java3d环境。

安装java3d时，需要安装以下exe并且把bin和lib拷到jdk的jre路径里。具体过程网上有，很简单。

然后跑一遍

importjava.applet.Applet;

importjava.awt.BorderLayout;

importcom.sun.j3d.utils.applet.MainFrame;

importcom.sun.j3d.utils.geometry.*;

importcom.sun.j3d.utils.universe.*;

importjavax.media.j3d.*;

importjavax.vecmath.*;

importcom.sun.j3d.utils.behaviors.mouse.MouseRotate;

importcom.sun.j3d.utils.behaviors.mouse.MouseZoom;

importcom.sun.j3d.utils.behaviors.mouse.MouseTranslate;

public classUglyCube extends Applet

{

privateSimpleUniverse universe ;

public UglyCube()

{}   

public void init()

{     

     //canvas to draw on, ask SimpleUniversewhat config to use    

     Canvas3D canvas = newCanvas3D(SimpleUniverse.getPreferredConfiguration());     

     setLayout(new BorderLayout());     

     add("Center", canvas);          

     //create top of our scene graph     

     BranchGroup scene = newBranchGroup();              

     //create universe, and attach our geometryto it.     

     SimpleUniverse u = newSimpleUniverse(canvas);     

    u.getViewingPlatform().setNominalViewingTransform();             

     // Create the bounding leaf node

     BoundingSphere bounds = newBoundingSphere(new Point3d(0.0,0.0,0.0), 100.0);

     // Create the transform node

     TransformGroup transformGroup = newTransformGroup();

    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 = newMouseTranslate();

    behavior3.setTransformGroup(transformGroup);

     transformGroup.addChild(behavior3);

     behavior3.setSchedulingBounds(bounds);

     transformGroup.addChild(newColorCube(0.4));

 

     scene.addChild(transformGroup);   

     u.addBranchGraph(scene);

}   

 

// The followingallows UglyCube to be run as an application   

// as well as anapplet   

public static voidmain(String[] args)

{       

     new MainFrame(new UglyCube(), 256,256);  

}

}

 

发现报错，没有javax.media.j3d包。需要在oracle官网上下载下载java媒体框架并安装

 

再跑，又报错。Can't load IA 32-bit .dll on a AMD 64-bit platform。一开始百度查的都说是tomcat的问题，我也没用到tomcat，仔细看了半天发现是一个dll的问题。需要用64位而不是32位的j3dcore-ogl.dll

下载好之后，把这个dll放到之前jdk的jre路径的bin里替换。然后终于能跑通上面的uglycube了

注意，编译是javacuglycube.java，运行是java uglycube，不要加.class

 

跑通证明java3d已经安装好，这时候用命令行打开simbad：java-jar simbad-1.4.jar就可以打开了，里面有很多自带样例

 

官方说明见http://simbad.sourceforge.net/guide.php#controller

 

关于创建机器人，官方给了代码，要创建三个.java文件，在编译的时候用javac -classpath simbad-1.4.jar *.java

在运行的时候用java-classpath simbad-1.4.jar;. MyProg
