[vtkusers] VTK and OpenGL

[Steffen Oeltze]

Dear VTK-gurus,

as I learned VTK is based on OpenGL. Is there a possibility to integrate VTK-
commands directly into an OpenGL-program ? I've written a simple application 
including the typical methods main(), init(), reshape(w,h), display(). I'd like 
to keep this structure and integrate VTK-commands for volume rendering.

Any suggestions and hints will be appreciated,
Kind Regards,
Steffen Oeltze
