igl::edges
void edges(const Eigen::MatrixBase< DerivedF > &F, Eigen::PlainObjectBase< DerivedE > &E)
Constructs a list of unique edges represented in a given mesh (V,F)

igl::fast_find_self_intersections
bool fast_find_self_intersections(const Eigen::MatrixBase< DerivedV > &V, const Eigen::MatrixBase< DerivedF > &F, Eigen::PlainObjectBase< DerivedI > &intersect, Eigen::PlainObjectBase< DerivedE > &edges)
Identify triangles where mesh intersects itself using AABBTree and tri_tri_intersection_test_3d.

igl::intersect
void intersect(const M &A, const M &B, M &C)
Determine the intersect between two sets of coefficients using ==.
