This works if the point is nearby. If i click e.g. in the middle of a 
triangle of medium size (unstructured mesh) it does not select a point. 
The problem is: exploring a solution i am not interested in the points 
but in the flow field and so normally i do not show the points but a 
e.g. a cut with a scalar. There i would like to get information about 
this scalar ...

The case has about 20e6 points and there is only a cut visible. 
Rendering the clicked point it takes about 5 secs ...
