Vector gamer::getNormal(const SurfaceMesh &mesh, SurfaceMesh::SimplexID<3> faceID)¶
Compute the normal of a face.
This function computes the normal as the cross product with respect to the orientation. See also getTangent() and getNormalFromTangent().
- Parameters
mesh – [in] SurfaceMesh of interest.
faceID – [in] SimplexID of the face to get the tangent of.
- Returns
Returns a Vector normal to the face.
