How to dynamically update vtkTextActor input in an animation?

I have a 3D simulation done in VTK with a text actor which displays the current runtime. My inefficient way of doing that is creating a vtkTextActor object in each frame which holds the current runtime in seconds as input and deleting the TextActor from the last frame. All of that happens inside a repeating vtkTimerCallback function. On each frame I create and delete a vtkTextActor. Is there a way to dynamically update the SetInput() method of vtkTextActor and then showing the new text on each execution of vtkTimerCallback? In other words - using the same vtkTextActor and updating it on each frame rather than creating\deleting actors. -- Sent from: http://vtk.1045678.n5.nabble.com/VTK-Users-f1224199.html _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the VTK FAQ at: http://www.vtk.org/Wiki/VTK_FAQ Search the list archives at: http://markmail.org/search/?q=vtkusers Follow this link to subscribe/unsubscribe: https://vtk.org/mailman/listinfo/vtkusers
