I am writing a program which will have realtime updates to the
displayed data under C++ using VTK under Windows. I have tried using a
vtkRenderWindowInteractor. Unfortunatly, vtkRenderWindowInteractor only
seems to preform updates when the user is interacting with the scene. I
need to refresh the window anytime my data changes. At the present
time, I am trying to following solution:
Create the window, interactor, and renderer and associate
appropriatly. Then create my worker thread whose job it will be to
periodically update the vtkActors which are being displayed. I then
start the interactors event loop with interactor->Start();. I have
tried having the thread update the screne by calling the render methods
of both vtkRenderWindowInteractor and vtkRenderWindow (not at the same
time of course). However, I get error messages related to something
about wgl not being able to make the current context. Can anyone show
me some code or suggest how I can both use an Interactor with a scene
that must be updated even when the user is not interacting with the data
Thanks in advance.
