UnsupportedNodeException:请求不属于指定配置文件的节点和此流的组件:视图

Question

我已经坚持了一段时间同样的问题,我不知道为什么运行我的项目时出现以下运行时错误.

Exception in thread "main" org.web3d.vrml.lang.UnsupportedNodeException: Request for a node that is not part of the specified profile and components for this stream: viewpoint

我的Java代码是

package xj3dtest;

import java.awt.BorderLayout;
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_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.xj3d.ui.awt.browser.ogl.X3DOGLBrowserFactoryImpl");
        X3DComponent x3dComponent = BrowserFactory.createX3DComponent(requestedParameters);

        Browser browser = x3dComponent.getBrowser();

        Container cp = getContentPane();
        cp.setLayout(new BorderLayout());
        cp.add((javax.swing.JPanel)x3dComponent, BorderLayout.CENTER);

        X3DScene scene = browser.createX3DFromURL(new String[] {"test.x3d"});

        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);
    }
}

X3D我需要通过它的文件,因此它显示包含一个viewpoint和imageTexture url标签,经过测试导致问题.当我从X3D文件中删除这些标签时,它确实有效但没有所需的输出,因为它似乎被放大并且X3D文件没有纹理.

在Jars我使用的gluegen-rt, gluegen-rt-natives-linux-amd64, gluegen-rt-natives-windows-amd64, gluegen-rt-natives-linux-i586, j3d-core-1.3.1, jhall, joal, joal-natives-linux-amd64, joal-natives-windows-amd64, joal-natives-linux-i586, joal-all, joal-all-natives-linux-amd64, joal-all-natives-windows-amd64, joal-all-natives-linux-i586, xj3d.browser_2.1.0-nps, xj3d.cadfilter_2.1.0_nps, xj3d.2.1-3rdparty-nps, xj3d.2.1-nps, xj3d-core, xj3d-runtime, xj3d-script-base.我设置VM选项的方法是使用-Xmx450M -Djava.library.path="C:\Users\matt\Documents\NetBeansProjects\jar",我已经添加了包含Jars项目所有内容的库.

编辑 它仍然无法正常工作

编辑#2

导致问题的两个标签是

<viewpoint centerOfRotation="7 1 0" position='10 0 40' orientation='0 0 0 1'></viewpoint>

<imageTexture url='"http://somewebsite.com/images/test.jpg"></imageTexture> 请记住,上述网站不是存储图像的网站,但它遵循相同的格式.

编辑#3

X3D现在文件中 的代码<viewpoint centerOfRotation="7 1 0" position='10 0 40' orientation='0 0 0 1'></viewpoint>

<imageTexture url="http://somewebsite.com/images/test.jpg"></imageTexture>

我仍然得到视点错误,我不知道如何解决它

Answer 1

对于第一个标签，错误显然是url属性上的虚假单引号。

对于第二个，您可以尝试对所有属性使用一致的引号，一些解析器恰好在这方面失败。

在全球范围内，您可以从这里开始：

• 使用此验证器等工具检查 XML 的格式良好性
• 检查您的 X3D 是否与 XML 标头中声明的 xsd 有效。此页面上有一些验证器的参考资料，但最有效的方法仍然是使用您选择的 XML 创作工具。
