[vtkusers] Matrix application with filters

I have this problem: I have a dataset with a set of points (x,y,z,1). They are the points of a Polydata.
I need to project them onto a plane. to do so I need to compute (x/z, y/z, z/z,1), where z dependes on the current point.
If z was constant the matrix would be easy to build and I could set a PolyDataFilter to apply it all over the polydata. But as Z is the 3rd coordinate of each point itself... is there a way to dofine a matrix or a filter which does what I would like to do?
Otherwise I would scrool through the entire dataset, point by point, shoudn't I?
