Abstract

We introduce a parametrized notion of genericity for Delaunay triangulations which, in particular, implies that the Delaunay simplices of $\delta$-generic point sets are thick. Equipped with this notion, we study the stability of Delaunay triangulations under perturbations of the metric and of the vertex positions. We then show that, for any sufficiently regular submanifold of Euclidean space, and appropriate $\epsilon$ and $\delta$, any sample set which meets a localized $\delta$-generic $\epsilon$-dense sampling criteria yields a manifold intrinsic Delaunay complex which is equal to the restricted Delaunay complex.
