Viewing Volume Visualizer is a tutorial tool for understanding viewing and projection in OpenGL. It allows user to see effects of changing viewing and projection parameters on seeing a scene. Additionally it is possible to dump a C file which specifies viewing and projection of the current principal view in one routine. It could be incorporated into another program that wants to define a specific view and projection. VVV can therefore be used as a preview tool.
