[vtkusers] vtkPoints->ComputeBounds

[Yan Pingkun]

Hi all,
 
I'm trying to modify vtkPolyData by getting vtkPoints and the point
values are changed successfully. But the problem is that I want to can't
update the bounds. I called vtkPoints->ComputeBounds(), but it doesn't
work. I traced into the source code and found the condition
=======================
if ( this->GetMTime() > this->ComputeTime )
=======================
is always false. Hence, the bounds can't be updated.
 
Anybody can help?
 
Thanks!
 
Regards,
Pingkun
