- Some MITK classes easily use the mitk::RenMan::GetInstance() singleton.
- This limits the RenMan usage to the global instance and is prone to errors
If an application uses some render windows with varying data in differing parts of the application, we want to have the possibility to manage the rendering process independent for each window.
Thus, the rendering manager should always be instantiated by means of:
mitk::BaseRenderer::GetInstance(vtkRenderWindow*)->GetRenderingManager()
core modification requested, some spec will be provided.
