Q: How to make normal point outward?

[J. Scott Pendergrass]

<x-flowed>VTK Gurus:

I've got a 3D object that is defined in vtkPolyData form. I'd like to make 
sure that all of the polygon normals point "outward" in the right-hand rule 
sense. Is there an easy way to do this within VTK?

Thanks in advance,

Scott
