Question

我试图创建一个将X3D文件加载到Java中的项目以及用于Java显示它们的项目，我使用Xj3D来执行此操作但是当我运行代码时，我似乎遇到了错误。我已经下载了here列出的所有邮箱。我创建了一个名为“Xj3D＆＃39;在项目属性中，在库部分，我已经放了Xj3D库，在VM选项中，我放了-Xmx450M -Djava.library.path='C:\Users\matt\Downloads\xj3d-sai_2.0.0.jar'，我在java中的代码是：

package xj3dtest;

import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.Container;
import static java.lang.Boolean.TRUE;
import javax.swing.JFrame;
import org.web3d.x3d.sai.Browser;
import org.web3d.x3d.sai.BrowserFactory;
import org.web3d.x3d.sai.X3DComponent;
import org.web3d.x3d.sai.X3DScene;
import java.util.HashMap;

public class Xj3DTest extends JFrame {

    public Xj3DTest(String title) {

        super(title);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // Setup browser parameters
        HashMap requestedParameters=new HashMap();
        requestedParameters.put("Antialiased",TRUE);
        requestedParameters.put("TextureQuality","MEDIUM");
        requestedParameters.put("PrimitiveQuality","MEDIUM");
        requestedParameters.put("Xj3D_InterfaceType","SWING");
        requestedParameters.put("Xj3D_NavbarShown",TRUE);
        requestedParameters.put("Xj3D_NavbarPosition","TOP");
        requestedParameters.put("Xj3D_LocationShown",TRUE);
        requestedParameters.put("Xj3D_LocationPosition","TOP");
        requestedParameters.put("Xj3D_LocationReadOnly",TRUE);
        requestedParameters.put("Xj3D_ShowConsole",TRUE);
        requestedParameters.put("Xj3D_OpenButtonShown",TRUE);
        requestedParameters.put("Xj3D_ReloadButtonShown",TRUE);
        requestedParameters.put("Xj3D_StatusBarShown",TRUE);
        requestedParameters.put("Xj3D_FPSShown",TRUE);
        requestedParameters.put("Xj3D_ContentDirectory","CurrentDirectory");
        requestedParameters.put("Xj3D_AntialiasingQuality","LOW");
        requestedParameters.put("Xj3D_Culling_Mode", "frustum");

        System.setProperty("x3d.sai.factory.class", "org.web3d.ogl.browser.X3DOGLBrowserFactoryImpl");
        X3DComponent x3dComponent = BrowserFactory.createX3DComponent(requestedParameters);

        Browser browser = x3dComponent.getBrowser();

        Component browserComponent = (Component)  x3dComponent.getImplementation();

        Container cp = getContentPane();
        cp.setLayout(new BorderLayout());
        cp.add(browserComponent, BorderLayout.CENTER);

        X3DScene scene = browser.createX3DFromURL(new String[]   {"test.x3dv"});

        browser.replaceWorld(scene);
    }

    public static void main(String[] args) {
        Xj3DTest frame = new Xj3DTest("Xj3D test");
        frame.setSize(640, 480);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}

我已将test.x3dv文件放在项目文件夹中。 test.x3dv代码如下：

#X3D V3.0 utf8

PROFILE Interactive

DEF TS TimeSensor {
  cycleInterval 3
  loop TRUE
}

DEF TG Transform {
  rotation 0 1 0 0
  children Shape {
    geometry Box {}
    appearance Appearance {
      material DEF MAT Material {
        diffuseColor 1 0 0
      }
    }
  }
}

DEF OI OrientationInterpolator {
  key [ 0 0.5 1 ]
  keyValue [
     0 1 0 0
     0 1 0 3.14
     0 1 0 6.28
  ]
}

ROUTE TS.fraction_changed TO OI.set_fraction
ROUTE OI.value_changed TO TG.rotation

当我按下Netbeans中的运行按钮时，我收到以下运行时错误：
