Viewdependent simplification of arbitrary polygonal environments
, 1997
"... Hierarchical dynamic simplification (HDS) is a new approach to the problem of simplifying arbitrary polygonal environments. HDS operates dynamically, retessellating the scene continuously as the user’s viewing position shifts, and adaptively, processing the entire database without first decomposing ..."

VisibilityBased PursuitEvasion in a Polygonal Environment
 International Journal of Computational Geometry and Applications
, 1997
"... This paper addresses the problem of planning the motion of one or more pursuers in a polygonal environment to eventually "see" an evader that is unpredictable, has unknown initial position, and is capable of moving arbitrarily fast. This problem was first introduced by Suzuki and Yamashita ..."

Randomized PursuitEvasion in a Polygonal Environment
, 2004
"... This paper contains two main results: First, we revisit the wellknown visibility based pursuitevasion problem and show that, in contrast to deterministic strategies, a single pursuer can locate an unpredictable evader in any simplyconnected polygonal environment using a randomized strategy. The ..."

Separating point sets in polygonal environments
 in Proceedings of the 20th Annual ACM Symposium on Computational Geometry
, 2004
"... We consider the separability of two point sets inside a polygon by means of chords or geodesic lines. Specifically, given a set of red points and a set of blue points in the interior of a polygon, we provide necessary and sufficient conditions for the existence of a chord and for the existence of a ..."

Capturing an evader in a polygonal environment with obstacles
 22nd International Joint Conference on Artificial Intelligence
"... We study a pursuitevasion game in which one or more cops try to capture a robber by moving onto the robber’s current location. All players have equal maximum velocities. They can observe each other at all times. We show that three cops can capture the robber in any polygonal environment (which can ..."

Complete information pursuit evasion in polygonal environments
 In Proc. of 25th Conference on Artificial Intelligence (AAAI
"... Suppose an unpredictable evader is free to move around in a polygonal environment of arbitrary complexity that is under full camera surveillance. How many pursuers, each with the same maximum speed as the evader, are necessary and sufficient to guarantee a successful capture of the evader? The pursu ..."

Smooth Feedback for CarLike Vehicles in Polygonal Environments
"... Abstract — We introduce a method for constructing provably safe smooth feedback laws for carlike robots in obstaclecluttered polygonal environments. The robot is taken to be a point with motion that must satisfy bounded path curvature constraints. We construct a global feedback plan (or control pol ..."
