[JAVA3D] Starfire 3DS Loader & Applet

[Nuno Pereira]

Hello,

I'm trying to use the Starfire 3DS Loader but not with success.
I'm writing an applet that load a 3ds file from an URL. I'm using the new
2.0 version of the loader.
When I test the applet with AppletViewer it works, but when I use the
Browser (IE 5) it doesn't work. I get the message "Start: applet not
initialized".
I'm using Java Plug In 1.3.
Can anyone help me?

Thanks in advance,
Nuno Pereira

Here is my code:

package pt.vwater;

import java.applet.Applet;
import java.awt.*;
import javax.media.j3d.BranchGroup;
import javax.media.j3d.Canvas3D;
import javax.media.j3d.Transform3D;
import javax.media.j3d.TransformGroup;
import javax.media.j3d.View;
import javax.media.j3d.BoundingSphere;

import com.sun.j3d.utils.universe.SimpleUniverse;
import com.mnstarfire.loaders3d.Inspector3DS;


public class Viewer extends Applet {

  private java.net.URL filename;

  public Viewer() {}

  public void init()
  {
    // Construct the applet canvas
    setLayout(new BorderLayout());
    GraphicsConfiguration config =
    SimpleUniverse.getPreferredConfiguration();

    Canvas3D c = new Canvas3D(config);
    add("Center", c);

    // Create a basic universe setup and the root of the scene
    SimpleUniverse u = new SimpleUniverse(c);
    u.getViewingPlatform().setNominalViewingTransform();
    BranchGroup sceneRoot = new BranchGroup();


    // the path to the file for an applet
    try
    {
      java.net.URL path = getCodeBase();
      filename = new java.net.URL(path.toString() + "./D1.3ds");
    }
    catch (java.net.MalformedURLException ex)
    {
      System.out.println(ex.getMessage());
      System.exit(1);
    }

    Inspector3DS loader = new Inspector3DS(filename);
    loader.setURLBase(getCodeBase().toString());
    loader.parseIt();
    TransformGroup max = loader.getModel();
    sceneRoot.addChild(max);

    AmbientLight amblight = new AmbientLight();
    amblight.setColor(new Color3f(0.0f, 0.325f, 0.494f));
    amblight.setInfluencingBounds(new BoundingSphere(new Point3d(0, 0, 0),
100.0));
    sceneRoot.addChild(amblight);

    DirectionalLight dirlight = new DirectionalLight();
    dirlight.setCapability(Light.ALLOW_STATE_WRITE);
    dirlight.setColor(new Color3f(0.0f, 0.325f, 0.494f));
    dirlight.setInfluencingBounds(new BoundingSphere(new Point3d(0, 0, 0),
100.0));
    sceneRoot.addChild(dirlight);

    u.addBranchGraph(sceneRoot);
  }
}
