[vtkusers] vtkPoints->ComputeBounds

[Yan Pingkun]

Hi,
 
I have solved this problem by calling vtkPoints->Modified() before
computing bounds. But I wonder if this should be done by the objects
implicitly?

	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
