Hi, Community,

Recently I have just begun to do some research about parallel rendering with VTK. It’s so wonderful that VTK has provided many interfaces for user to call for. However it’s wired that I just could find vtkTreeCompositer under vtkCompositer. For some reasons that I need to use 2-3 Swap algorithm to combine image. So I wonder whether the algorithm has implemented in somewhere or not. If not, how can I implement the algorithm rapidly?
