[vtkusers] Color the 3D object wrt the time when the points were added

[Divya]

Dear All,

I am working on an application where I am adding 1 point at a time and 
the 3D object is re-rendered. I need to color this 3D object with 
respect to the time when the points were added.

The final object  is rendered after the vtkButterflySubdivisionFilter. I 
have implemented a timer with an interval of 20 secs, and I need to 
change the colors of the 3D object every 20 secs, ie : The region that 
was created within the last 20 secs should be rendered in 'red' color, 
and the region created in the previous 20secs in another color and so on.

Is there a way to implement this in VTK? Also is there a way to get the 
points in the last modified region?

Thanks in advance!
