[vtkusers] Picking objects in VTK and java

[Christian Bleiholder]

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
