Voronoi diagram in presence of polygonal obstacle

Suppose there is a set of convex polygons ($\mathbb{P}$) on the plane. For each convex polygon $P_i$ there is one "facility" $f_i$ placed on the boundary of $P_i$. The distance between a point $p \in ...

Voronoi diagrams applications where the input order has some known properties?

Are there applications of Voronoi diagrams or Delaunay triangulations where the order in which the points are generated (and given to the algorithm) have some known properties (e.g. concatenation of ...

Outer part of Voronoi diagram in 3D

Given a set of points $V \subset \mathbb{R}^d$, the Voronoi diagram divides $\mathbb{R}^d$ into $|V|$ parts such that for every $v \in V$, the part of $\mathbb{R}^d$ for which $v$ is closer than any ...

Sampling from the Voronoi cell of a point

Fix a set of $n$ points $P \subset \mathbb{R}^d$. Now a query point $q$ arrives, and the goal is produce a point $r$ sampled uniformly at random from the Voronoi cell of $q$ in the set $P \cup \{q\...
