I haven't replied because I don't know!  That's why always cc'ing the

My guess would be that you need to derive your own actor or renderer (?) 
that uses your own OpenGL code.  My suggestion would be to look at the 
Doxygen-generated documentation for vtk 
(http://www.vtk.org/doc/release/5.0/html/hierarchy.html) and work out 
where (if anywhere) your new rendering code would fit in the class 
hierarchy.

Cheers,

Andrew.
