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

[Lorenzo]

Hi all;
I was wondering if there's a way in paraview to color surfaces (ie triangles in a stl file) by the direction of their normals (inwards or outwards).

Meaning, if you pick a triangle, one side of it will be of one color while the other side will be of a different color, depending on whether that triangle normal is point towards the triangle of away from it.


Thank you

Lorenzo
