Hi Vlad, take a look at this snippet of code,
it should show you how to use the vrml-loader. The actionlistener of
the button actually does the loading stuff.
Cheers Joerg
Here we go:
import com.sun.j3d.loaders.vrml97.VrmlLoader;
import com.sun.j3d.loaders.vrml97.VrmlScene;
import vrml.BaseNode;
JButton button3 = new JButton("Add Geometry");
button3.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
fc = new JFileChooser("Models/Geometry/");
fc.setSize(200, 200);
fc.setLocation(500, 400);
int returnVal = fc.showOpenDialog(UniverseSwingVrml.this);
if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
VrmlScene s = null;
VrmlLoader loader = new VrmlLoader();
System.out.println("Parent Pathname: " + file.getParent() + ".");
try {
s = (VrmlScene) loader.load(file.getParent()+ "/" +
file.getName());
} catch (FileNotFoundException fe) {
System.err.println(fe);
System.exit(1);
}
catch (vrml.InvalidVRMLSyntaxException fe) {
System.err.println("VRML parse error");
fe.printStackTrace(System.err);
}
// Transform the geometry
TransformGroup tg = new TransformGroup();
Transform3D t = new Transform3D();
t.set(new Vector3f(0f,1.5f,0f));
tg.setTransform(t);
BranchGroup bg = new BranchGroup();
bg.addChild(tg);
tg.addChild(s.getSceneGroup());
cgroot.addChild(bg);
}
}
});
