[vtkusers] Actor rotation

[Rao Jianguo]

Dear All,

I want to rotate a vector first around  z axis  ( this is prety easy by 
calling the RotateZ function )
and then rotate the actor along the new axes y ( let's call it y').  And 
finally rotate 
around the new axes Z ( let's call it z'' ).

I am pretty sure this is a simple question and should be implimented by 
somebody
but I can't find any example.  Anybody there can enlight me? A specific 
example will
be great help.

Your help is highly appreciated.
