[vtkusers] Using a Transformation matix to rotate an object

[Chris Hughes]

Hi Guys,

I am looking for some information on using Transformation Matrices in VTK. I
have a single actor which I want to rotate using a transformation trix, but
I can not find how to apply a matrix to the actor?

If you could point me towards a code sample, I would be most grateful! I am
using c++ under linux!

Thanks!

Chris
