[vtkusers] Picking objects in VTK and java

[R K Shyamprakash]

Hi,
      you can use vtkPicker. following is a code snippet.
vtkPropPicker picker = (vtkPropPicker)iren.GetPicker();//iren is
vtkRenderWindowInteractor
if(picker.Pick(e.getX(),(demo.renWin.getSize().height-e.getY()),0,demo.ren)
!= 0){
	double d1[] = picker.GetPickPosition();
}

make sure you apply proper mutex locking around thw Pick methid.

regards
Shyam

Dear all,

I am new to the VTK;  I use the Java wrapper to VTK 4.2
and I cannot solve the following task:

I use VTK to render some data structures like Spheres,etc.
I then want to be able to pick (by mouse) one of these VTK-spheres and do
some tasks with their underlying data structures.

Can anyone help me?

Regards,
 Christian
