[Paraview] Color surface by normal direction (inwards or outwards)

[Cory Quammen]

Lorenzo,

Yes, you can do this.

Under the Display tab, choose the color of the front face in the
"Color" control panel. Set the "Color by" option to Solid Color, then
pick the color you want with the "Set Solid Color..." button. Then
scroll down almost to the bottom of the Display tab. There is a
"Backface Style" panel. If you set the representation to Surface, you
can then pick the color of the backface.

You can do other things, to, such as turn on front face or back face
culling, which you might find useful.

Hope that helps,
Cory
