چکیده

〈Summary〉 Sampling patterns with a blue noise distribution are widely used in many areas of computer graphics, yet their efficient generation remains a difficult problem. We propose a method to generate point sets with a blue noise distribution using a deterministic algorithm with no preprocessing. We insert each new sample at the center of the largest empty circle in the point set, which is obtained by calculating the Delaunay-triangulation of the set and finding the triangle with the largest circumcircle. Our method supports adaptive sampling according to a user-specified density function, as well as specifying the exact number of required samples. It can also be extended to perform sampling on a three-dimensional curved surface.

Computing Largest Empty Circles with Location Constraints 1 ' 2

Let Q = {qj, qz,..., qn / be a set of n points on the plane. The largest empty circle (LEC) problem consists in finding the largest circle C with center in the convex hull of Q such that no point q(C Q lies in the interior of C. Shamos recently outlined an O(n log n) algorithm for solving this problemJ 9) In this paper it is shown that this algorithm does not always work correctly. A different ...

Largest empty circle centered on a query line

The Largest Empty Circle problem seeks the largest circle centered within the convex hull of a set P of n points in R2 and devoid of points from P . In this paper, we introduce a query version of this well-studied problem. In our query version, we are required to preprocess P so that when given a query line Q, we can quickly compute the largest empty circle centered at some point on Q and withi...

The Largest Empty Circle Problem

The largest empty circle (LEC) problem is defined on a set P and consists of finding the largest circle that contains no points in P and is also centered inside the convex hull of P . The LEC is always centered at either a vertex on the Voronoi diagram for P or on an intersection between a Voronoi edge and the convex hull of P . Thus, finding the LEC consists of constructing a Voronoi diagram a...

We propose a randomized search method called Stochastic Model Reference Adaptive Search (SMRAS) for solving stochastic optimization problems in situations where the objective functions cannot be evaluated exactly, but can be estimated with some noise (or uncertainty), e.g., via simulation. The method is a generalization of the recently proposed Model Reference Adaptive Search (MRAS) method for ...
