[vtkusers] Re: vtk rotation

Hi Jess,

If you are using the cube as an individual actor and you want to rotate 
it around the centre of the cube and it's local axis then you need to
specify it's origin (the point around which all rotations happen). So 
you'll need something like the following:

vtkCubeSource* cube = vtkCubeSource::New();
cube->SetCenter(x,y,z);

vtkPolyDataMapper* mapper = vtkPolyDataMapper::New();
mapper->SetInput(cube->GetOutput());

vtkActor* actor = vtkActor::New();
actor->SetMapper(mapper);
actor->SetOrigin(cube->GetCenter());

actor->RotateZ(z);

I hope this helps,
               Aroosha
