Thanks, my fellow graphics member, Manu!
However, it still complains with the same exception. (I even tried
PickTool.setCapabilities method.)
Can someone share an excerpt of code that has the picking a 3d object working?
Thank you,
Kovalan
Ps. Mine is as follows:
// Main:
pickCanvas = new PickCanvas(canvas, scene);
pickCanvas.setMode(PickTool.GEOMETRY );
pickCanvas.setTolerance(4.0f);
canvas.addMouseListener( new MouseClicked() );
// 3d Object creation
box.setCapability( Geometry.ALLOW_INTERSECT );
box.getShape(Box.BACK).setCapability( Geometry.ALLOW_INTERSECT );
box.getShape(Box.BOTTOM).setCapability( Geometry.ALLOW_INTERSECT );
box.getShape(Box.FRONT).setCapability( Geometry.ALLOW_INTERSECT );
box.getShape(Box.LEFT).setCapability( Geometry.ALLOW_INTERSECT );
box.getShape(Box.RIGHT).setCapability( Geometry.ALLOW_INTERSECT );
box.getShape(Box.TOP).setCapability( Geometry.ALLOW_INTERSECT );
// MouseClicked
class MouseClicked extends java.awt.event.MouseAdapter {
public void mouseClicked(java.awt.event.MouseEvent e) {
super.mouseClicked(e);
PickResult[] results = null;
try {
pickCanvas.setShapeLocation(e);
results = pickCanvas.pickAll();
}
catch ( Exception err ) {
err.printStackTrace();
System.out.println( "Err: Not pickable??" );
}
if ( results != null )
System.out.println( "Picked!" );
else
System.out.println( "Nothing happened!" );
}
}

Hi Kovalan,
If you want to pick using geometry (USE_GEOMETRY), you have to add the
capability Geometry.ALLOW_INTERSECT to the appropriate Geometry object (I
guess this is causing the "no capability to allow intersect" exception).
Regards,
Manu.
