Example text

We extend the definition to strata: Skli S|Di = Skli S|σ . 3 Refinement Our strategy is to run Delaunay refinement with only the disk condition formulated as follows. 2 for more explanations. Let p be a point on a 2-face σ. Let UmbD (p) and Umbσ (p) be the set of triangles in Skl2 S|D2 and Skl2 S|σ respectively which are incident to p. The following disk condition is used for refinement. Once the restricted Delaunay triangles are collected, this check is only combinatorial. Disk Condition(p) : (i) UmbD (p) = σ∋p Umbσ (p), (ii) for each σ ∈ D2 containing p, underlying space of Umbσ (p) is a 2-disk which has all vertices in σ.

Therefore, they connect only adjacent vertices on bd σ and are exactly the edges of Skl1 S|bd σ by T1. Case (iii): σ ∈ D3 . Let K = Skl3 S|σ . First we argue that if K is not empty then it has vertices only in σ. Suppose not. Then there is a tetrahedron in K one of whose vertex, say p, is in σ′ ∈ D where σ′ ⊆ σ. The dual Voronoi vertex, say v, of this tetrahedron is in σ by definition. The Voronoi cell of p intersects both σ and σ′ . Therefore there is a Voronoi edge of this Voronoi cell that intersects bd σ.
