vtkMultiChannel is a library that makes it easier to render multiple views of a scene using the Visualization ToolKit (VTK), an open-source, freely available software system for data visualization.  One nice feature of vtkMultiChannel is that it uses a single vtkRenderWindow/vtkRenderWindowInteractor/vtkRenderer combo, so you don’t need to worry about making sure multiple renderers are synchronized.  This code makes it easier to set up rendering for systems such as our passive-stereo TeleImmersion environment, and our immersive Showcase Dome environment.

Currently, only Windows is supported, but it should be easy to add support for other operating systems.  Also, picking with the mouse is currently broken.  vtkMultiChannelRenderWindowManager enables flexible creation of multi-channel rendering, whereas vtkRenciRenderWindowManager is a subclass of vtkMultiChannelRenderWindowManager that makes it easy to set up rendering for the TeleImmersion and Showcase Dome environments, as well as the head-mounted display device in UNC Computer Science.

The code can be found here.  CMake is use for set up.
