Summary0015758: vtkOpenGLPolyDataMapper2D (OpenGL2, VTK 6.3) update problem with TransformCoordinate
DescriptionAssuming we have:

vtkNew<vtkPolyDataMapper2D> m;
vtkNew<vtkCoordinate> coord;
coord->SetCoordinateSystemToWorld();
m->SetTransformCoordinate(coord.GetPointer());

Then use m with a 2D actor to display a polydata. The first render is fine. Now, rotate the view. The polydata rendered by m should rotate along, but it does not.

A simple solution is to call UpdateVBO more often. Of course, it is wasteful, but the old opengl backend did no better, so I think it would be acceptable. For instance, adding

  || (this->TransformCoordinate && this->VBOUpdateTime < viewport->GetMTime())


to the condition governing whether UpdateVBO is called seems to solve the problem in my case.

A better solution would be to not manually transform points and reflect the TransformCoordinate into the opengl matrix, but of course it is more work.
