<a target=\"_blank\" href="file:///F:/Softwares/Rakesh/vtk/"></a><br>Hi Darshan,<br><br>That i have done.. But how do i set the updated data
to the actor..??<br><br>I mean, for example, I get the Unstructured grid
from the actor as follows:<br><br>vtkUnstructuredGrid *grid =
vtkUnstructuredGrid::SafeCast( actor->GetMapper()->GetInput() );<br><br>vtkPoints
*pts = grid->GetPoints();<br><br>// Assign new values to pts<br><br>Next
how do I connect this pts to actor "actor" so that the actor clears the
old display and renders new display..??<br><br>I mean after i set pts
to grid, how do i set this grid to actor..? I tried doing this...<br><br>actor->GetMapper()->GetInput()->ShallowCopy(grid);<br>actor->Modified();<br><br>But
i found no change.. It is showing same old display.. <br><br>Any
suggestions..??<br><br>Thanks<br><br>Regards<br>Rakesh Patil<br><font color="#000000"><br></font><br><blockquote><br>---------- Original message ----------<br>From:Darshan Pai< darshanpai@gmail.com ><br>Date: 04 Apr 10 01:22:24<br>Subject: Re: [vtkusers] How to change data through Actor<br>To: Rakesh Patil <rakeshthp@in.com><br><br>You can always get your data back from the actor using Actor->GetMapper()->GetInput().
