Samajoontest lähtuva tõkestatud triangulatsiooni korral järgivad kolm nurkade küljed küll samajooni, kuid kolmnurgad ei pruugi rahuldada Delaunay triangulatsiooni tingimusi.
Setting the constrained property on a TIN does not alter the existing state of the triangulation. It only controls what happens from that point forward. Therefore, if breaklines are added prior to setting the constrained triangulation property, those features will remain unchanged. Any densification points added to enforce those breaklines will not be removed.
