It's still more simple to generate a unit test for me, and it will be easier for you to test your changes.
So, here's a simple test showing a color cube in a canvas 3D laid out with split panes:

import java.awt.GraphicsEnvironment;
import javax.media.j3d.*;
import javax.swing.*;
import com.sun.j3d.utils.geometry.ColorCube;
import com.sun.j3d.utils.universe.SimpleUniverse;

public class Canvas3DPositionTest {
  public static void main(String [] args) {
    // Create a simple scene with a rotated color cube
    BranchGroup root = new BranchGroup();
    Transform3D rotation = new Transform3D();
    rotation.rotX(Math.PI / 9);
    TransformGroup rotationGroup = new TransformGroup(rotation);
    root.addChild(rotationGroup);
    rotationGroup.addChild(new ColorCube(0.5f));
    
    // Add scene to a new canvas 3D
    GraphicsConfigTemplate3D gc = new GraphicsConfigTemplate3D();
    Canvas3D canvas = new Canvas3D(GraphicsEnvironment.getLocalGraphicsEnvironment().
        getDefaultScreenDevice().getBestConfiguration(gc));
    SimpleUniverse universe = new SimpleUniverse(canvas);
    universe.getViewingPlatform().setNominalViewingTransform();
    universe.addBranchGraph(root);

    // Build a GUI where the canvas 3D is supposed to be located at the top right 
    // of the frame and can be resized with split panes dividers
    JFrame frame = new JFrame("Canvas3DPositionTest");
    JSplitPane horizontalSplitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, 
        true, new JScrollPane(), canvas);
    horizontalSplitPane.setResizeWeight(0.5);
    JSplitPane verticalSplitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT, 
        true, horizontalSplitPane, new JScrollPane());    
    verticalSplitPane.setResizeWeight(0.5);
    frame.add(verticalSplitPane);
    frame.setSize(400, 400);
    frame.setVisible(true);
  }
}

Hope this will help.
