<br><br><blockquote>Hi Andrew,<br><br>Even I'm working on the similar application.. What exactly you are trying to implement?<br>I wanted to display filled contours (color bands) for each time step without changing the geometry.<br>If this is what you are actually trying to implement, then, I also faced this problem.. <br>And i used the second method, to solve it.. But when i run my application, system gets loaded,<br> as memory is consumed, for each time steps.<br><br>So, i'm also in search of more effective method.<br><br>May be any seniors here can help you out.<br><br>Regards<br>Rakesh Patil<br><br><br>---------- Original message ----------<br>From:"Ðндрей Траченко"< goodrone@gmail.com ><br>Date: 3 Jun 10 18:50:10<br>Subject: [vtkusers] Updating cell and point data of vtkDataSet<br>To: vtkusers@vtk.org<br><br>Hello,<br><br>I'm working on an application which solves dynamic FEM problems and<br>has an interactive GUI which should display current data in
real-time.<br>It also has a VTK pipeline containing filters, mappers and actors.<br>Source classes are vtkPolyData and vtkUnstructuredGrid.<br><br>What is the best way to update data fields (assuming geometry is not<br>changing)? I can think of these ways:<br>1) Overwrite data (tuples in vtkDataArray) on each step, and mark the<br>source as modified.<br>2) Create new vtkDataArrays on each step, remove old arrays in cell<br>and point data, add newly created arrays.<br><br>Which way is better? Or maybe there is a better one?<br><br>--<br>Andrew<br>_______________________________________________<br>Powered by <a href="http://www.kitware.com" target="_blank">www.kitware.com</a><br><br>Visit other Kitware open-source projects at <a href="http://www.kitware.com/opensource/opensource.html" target="_blank">http://www.kitware.com/opensource/opensource.html</a><br><br>Please keep messages on-topic and check the VTK FAQ at: <a href="http://www.vtk.org/Wiki/VT
