[vtkusers] Picking in Java

[Jingyi Jin]

Hi Carlos, 

I had the same problem before, a kind person gave me
the following suggestion, that was about point
picking, but I guess you can derive actor picking from
it as well. Good luck!

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
