[vtkusers] Mirroring the scene

[Dirk Fortmeier]

Hi all, 

for using VTK in a special Hardware setup, I need to mirror the
rendering output of VTK in y-direction. My first thought was to use
camera->SetUserTransform() together with a scaling transform (y-scaling
set to -1) to mirror the projection matrix. Without lighting this works
fine but using lighting things get messed up. To me it looks like the
normals are not affected by the projection or something like that.

Is there an other way to do mirroring or does someone know how to fix
the issue?

Regards,
Dirk
