JAVA3D環境變量配置

1.環境需要

(1)JDK(我使用的是1.8版本的)不要用太高的版本下載下傳位址連結：https://pan.baidu.com/s/1FDvJcG5SMdWxl3fVnRbmRw 

提取碼：6cdp 

(2)需要JAVA3D插件的安裝下載下傳路徑為:https://download.csdn.net/download/hongfei568718926/11670370

安裝的時候選對你的JDK的版本32或者64位,對應不同的安裝,安裝過程傻瓜式安裝,

(3)必要的JAVA3D的jar包,下載下傳位址https://download.csdn.net/download/hongfei568718926/11670445

下載下傳後jar包放在G:\Java\JDK\jre\lib\ext這個目錄下面(注意路徑)

(4)運作的時候報

1. Exception in thread "main" java.lang.UnsatisfiedLinkError: no j3dcore-ogl in java.library.path這個錯誤的時候需要下載下傳j3dcore-ogl.dll檔案,下載下傳路徑https://download.csdn.net/download/hongfei568718926/11670416
2. 并放在G:\Java\JDK\bin這個目錄下面(注意路徑)

2.測試程式

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
import javax.vecmath.*;
import javax.media.j3d.*;

public class line1 extends Applet{
	BranchGroup createSceneGraph(){
		BranchGroup objRoot = new BranchGroup();
		float vert[] = {	
			0.0f,0.0f,0.0f,		
			0.5f,0.3f,0f,		
			-0.4f,0.1f,0.0f,	
			0.4f,-0.4f,0f};
		float color[] = {	1.0f,0.5f,1.0f,		0.5f,0.0f,1.0f,		0.0f,0.8f,0.0f,		1.0f,0.8f,0.0f};
		//建立LineArray執行個體line  沒兩點畫一個線
		LineArray line = new LineArray(4,LineArray.COORDINATES|LineArray.COLOR_3);
		//設定Line的坐标數組和顔色數組
		line.setCoordinates(0,vert);
		line.setColors(0,color);
		//定義一個Shape3D執行個體，并将line賦給Shape3D
		Shape3D shape = new Shape3D();
		shape.setGeometry(line);
		objRoot.addChild(shape);
		//定義一個白色的背景
		BoundingSphere bounds = new BoundingSphere(new Point3d(0.0,0.0,0.0),100);
		
		Color3f bgColor = new Color3f(1.0f,1.0f,1.0f);
		Background bg = new Background(bgColor);//背景顔色
		
		bg.setApplicationBounds(bounds);
		objRoot.addChild(bg);
		objRoot.compile();
		return objRoot;
	}
	//建立三維場景圖
	public line1(){
		setLayout(new BorderLayout());
		GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration();
		Canvas3D c = new Canvas3D(config);
		add("Center",c);
		BranchGroup scene = createSceneGraph();
		SimpleUniverse u = new SimpleUniverse(c);
		u.getViewingPlatform().setNominalViewingTransform();
		u.addBranchGraph(scene);
	}
	public static void main(String[] args){
		new MainFrame(new line1(),200,200);
	}
}
