Are you hoping that this will make its way into the main VTK repo or is this personal code that you plan on maintaining yourself and plan on linking with VTK?<br><br>There are people that know more about this than me but this sounds like a bad idea for the main VTK repo. A lot of the OpenGL specific calls are hidden by factories which create them as needed. For example, you'd create a vtkPolyDataMapper and the factory would create the vtkOpenGLPolyDataMapper, vtkMesaPolyDataMapper, etc as needed by the build.<br>

This is more of a design question anyway and relates to how to VTK classes are designed.</span></div>
