WebWe prove that planar pseudotriangulations have realizations as polyhedral surfaces in three-space. Two main implications are presented. The spatial embedding leads to a novel flip operation that allows for a drastic reduction of flip distances, especially between (full) triangulations. Moreover, several key results for triangulations, like flipping to … WebIt is known that computing the flip distance between two triangulations of a simple polygon or of a point set is NP-hard. The latter is known to be fixed-parameter tractable [ 33 ].
