[vtkusers] How to change data through Actor

[Rakesh Patil]

 Hi Darshan,That i have done.. But how do i set the updated datato the actor..??I mean, for example, I get the Unstructured gridfrom the actor as follows:vtkUnstructuredGrid *grid =vtkUnstructuredGrid::SafeCast( actor>GetMapper()>GetInput() );vtkPoints*pts = grid>GetPoints();// Assign new values to ptsNexthow do I connect this pts to actor "actor" so that the actor clears theold display and renders new display..??I mean after i set ptsto grid, how do i set this grid to actor..? I tried doing this...actor>GetMapper()>GetInput()>ShallowCopy(grid);actor>Modified();Buti found no change.. It is showing same old display.. Anysuggestions..??ThanksRegardsRakesh Patil Original message From:Darshan Pai< darshanpai at gmail.com >Date: 04 Apr 10 01:22:24Subject:Re: [vtkusers] How to change data through ActorTo: Rakesh Patil You can always get your data back from the actor using Actor>GetMapper()>GetInput(). Then you can change your data .On Sat, Apr 3, 2010 at 5:30 AM, Rakesh Patilwrote: He
 llo Users,I came to know that it is possible to change the data of a grid using actors. for example, I have already displayed a polyline. Now using this polyline actor, is it possible to change the number of points in this polyline..??Changing means i want it to reflect back on the render window..Any idea how to do this..??ThanksRakesh Patil Dear vtkusers !
