int t8_eclass_compare(t8_eclass_t eclass1, t8_eclass_t eclass2)

Compare two eclasses of the same dimension as necessary for face neighbor orientation. The implemented order is Triangle < Square in 2D and Tet < Hex < Prism < Pyramid in 3D.

Parameters:

eclass1 – [in] The first eclass to compare.
eclass2 – [in] The second eclass to compare.

Returns:

0 if the eclasses are equal, 1 if eclass1 > eclass2 and -1 if eclass1 < eclass2
