[vtkusers] vtkPicker in Java

[Karin Faulhaber]

Hi Jingyi,

I've included some own code in a local copy of vtkPanel (so I'm not
usingthe original one but the local one. And I'm not using any
Interactors. It's still OK for me). It looks like this:

if ('p' == keyChar) {
      	Render();
      	vtkPointPicker pPicker = new vtkPointPicker();
     	pPicker.Pick(lastX,getSize().getHeight()-lastY,0.0,ren);
      	int pickedPointId = pPicker.GetPointId();
	...
	...
}


Hope this helps
Karin
