我使用 Maya 2011 制作了一个 3D 模型,并使用加载器在 Java 3D 应用程序中进行访问。我已将该文件导出为 OBJ 文件,并在我的类中使用了 OBJ 文件加载器。然而,当我运行该应用程序时,我得到的只是一个空的黑屏。
这是我的代码:
import com.sun.j3d.loaders.objectfile.ObjectFile;
com.sun.j3d.loaders.ParsingErrorException;
import com.sun.j3d.loaders.IncorrectFormatException;
import com.sun.j3d.loaders.Scene;
import java.applet.Applet;
import java.awt.*;
import com.sun.j3d.utils.applet.MainFrame;
import com.sun.j3d.utils.universe.*;
import com.sun.j3d.utils.geometry.ColorCube;
import javax.media.j3d.*;
import javax.vecmath.*;
import java.io.*;
public class ObjLoad extends Applet {
public ObjLoad() {
setLayout(new BorderLayout());
GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration();
Canvas3D canvas3D = new Canvas3D(config);
add("Center", canvas3D);
BranchGroup scene = createSceneGraph();
scene.compile();
// SimpleUniverse is a Convenience Utility class
SimpleUniverse simpleU = new SimpleUniverse(canvas3D);
// This moves the ViewPlatform back a bit so the
// objects in the scene can be viewed.
simpleU.getViewingPlatform().setNominalViewingTransform();
simpleU.addBranchGraph(scene);
} // end of ObjLoad (constructor)
public BranchGroup createSceneGraph() {
// Create the root of the branch graph
BranchGroup objRoot = new BranchGroup();
String filename = "C:/Users/myName/Documents/maya/projects/GettingStarted/scenes/temple.obj";
ObjectFile f = new ObjectFile();
Scene s = null;
try {
s = f.load(filename);
}
catch (FileNotFoundException e) {
System.err.println(e);
System.exit(1);
}
catch (ParsingErrorException e) {
System.err.println(e);
System.exit(1);
}
catch (IncorrectFormatException e) {
System.err.println(e);
System.exit(1);
}
objRoot.addChild(s.getSceneGroup());
return objRoot;
} // end of createSceneGraph method
// The following allows this to be run as an application
// as well as an applet
public static void main(String[] args) {
Frame frame = new MainFrame(new ObjLoad(), 500, 500);
} // end of main (method of ObjLoad)
} // end of class ObjLoad
如果有任何帮助,我将不胜感激。
最佳答案
您的场景包含任何灯光吗?尝试将环境光设置为中度灰色。
