BrepMesh::Mesh, unit outward normal
I'm using BrepMesh::Mesh to triangulate the faces of a solid, and BRrep_Tool::Triangulation to extract the triangles for a given face.
What would be correct method to determine the unit outward normal to a triangle?
That is, what would be the correct way to determine the sign of the normal, if it should point outwards? Is it possible to deduce this information from the orientation of the vertices?
Thank you for your patience,
