"WebDobkin and Snyder [1] originally claimed to have a generic linear-time algorithm for nding the largest inscribed k-gon inside a convex polygon (for constant k), but this claim was later retracted: Boyce et al. [11] observe that the algorithm by Dobkin and Snyder fails for k= 5 and instead present a O(knlogn+nlog2 n) " - Dobkin and kirkpatrick's algorithm

WebBuild the Kirkpatrick point location hierarchy for the triangulation shown below. At each step, when you identify an independent set, apply Algorithm 7.4 on page 277, breaking ties when you select a node in favor of the lowest numbered vertex. When you retriangulate a hole, use the simple ear-clipping algorithm (Triangulate, page 39), Webadditional motivation in mind. We explain: The Dobkin -Kirkpatrick hierarchy 2 is a compact representation of a convex polytope that supports logarithmic -time collision detection. The main limitation of the method is that it requires convexity. Commonly, 3D objects (say, in medical imaging) appear convex from a distance,
