Your source code is available on Github but I haven't found yet the classes that rely on Java3D. Several JOGL users have already switched from Java3D to Ardor3D or use them both, this is still a challenge but it's worth the change.

The most important class that uses Canvas3D is pl.edu.icm.visnow.geometries.viewer3d.Display3DPanel

Can't you use an existing method of SwingUtilities instead of getTopmostComponent?

I assume you mean SwingUtilities.getWindowAncestor? Sure I can :)
I'd also add some security for backward compatibility on Java 6.

As a result we have:

import java.awt.Container;
import java.awt.GraphicsConfiguration;
import java.awt.Window;
import java.awt.event.HierarchyEvent;
import java.awt.event.HierarchyListener;
import java.lang.reflect.Method;
import javax.media.j3d.Canvas3D;
import javax.swing.JComponent;
import javax.swing.SwingUtilities;
