<DIV><FONT face=Arial size=2><SPAN class=755321803-26032004>I have solved this
problem by calling vtkPoints->Modified() before computing bounds. But I

<DIV><SPAN class=840283816-25032004><FONT face=Arial size=2>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</FONT></SPAN></DIV>
