[vtkusers] a tricky c++ problem...

Dear VTK-experts,

I have derived a class from vtkOpenGLActor, called myActor. I'd like 
this class
to hold a private variable that is a pointer to a user-provided volume. 
( To receive
a void pointer to the volume I use volume->GetScalarPointer() ) However, 
since
the user selects a volume which can be of different data types I don't 
know in
advance how to initialize the pointer in my class. I was told to use a 
template class
but I'm not a c++ expert and I was wondering if there is an easier way ?

Thanks in advance,
Steffen
