Improvements to algorithms for computing the Minkowski sum of 3-polytopes
收藏 引用
COMPUTER-AIDED DESIGN 2003年 第13期35卷 1181-1192页
作者: Wu, YY Shah, JJ Davidson, JK Arizona State Univ Coll Engn & Appl Sci Design Automat Lab Dept Mech & Aerosp Engn Tempe AZ 85287 USA
A Minkowski sum is a geometric operation that is equivalent either to the vector additions of all points in two operands or to the sweeping of one operand around the profile of the other without changing the relative ... 详细信息

Optimal and approximate bottleneck Steiner trees
收藏 引用
OPERATIONS RESEARCH LETTERS 1996年 第5期19卷 217-224页
作者: Ganley, JL Salowe, JS QUESTECH INC FALLS CHURCH VA 22043 USA
Given a set of terminals in the plane, a bottleneck Steiner tree is a tree interconnecting the terminals, in which the length of the longest edge is minimized. The bottleneck Steiner tree problem, or special cases the... 详细信息

IMPLEMENTATION OF A RANDOMIZED ALGORITHM FOR DELAUNAY AND REGULAR TRIANGULATIONS IN 3 DIMENSIONS
收藏 引用
COMPUTER AIDED geometric DESIGN 1995年 第4期12卷 349-370页
作者: FACELLO, MA UNIV ILLINOIS DEPT COMP SCI URBANA IL 61801 USA
For a set of n points in R3, we can define the Delaunay triangulation of the point set. For each assignment of weights to the points there is a regular triangulation of the point set. We describe the implementation of... 详细信息

A fan growing algorithm for efficient vertex caching
收藏 引用
COMPUTERS & GRAPHICS-UK 2003年 第5期27卷 773-789页
作者: Franzetti, T Day, AM Arnold, DB Univ E Anglia Sch Informat Syst Norwich NR4 7JT Norfolk England
In this paper we describe an algorithm to speed up the rendering of triangulated meshes. The gap between the microprocessor's speed and the memory's speed continuously increases so it is important to address, ... 详细信息

On the design of traps for feeding 3D parts on vibratory tracks
收藏 引用
ROBOTICA 2008年 第4期26卷 537-550页
作者: Goemans, Onno C. van der Stappen, A. Frank Univ Utrecht Inst Comp & Informat Sci NL-3508 TB Utrecht Netherlands
In the context of automated feeding (orienting) Of industrial parts, We Study the algorithmic design of traps in the bowl feeder track that filter Out all but one orientation of a given , polyhedral part. We propose a... 详细信息

Continuous point projection to planar freeform curves using spiral curves
收藏 引用
VISUAL COMPUTER 2012年 第1期28卷 111-123页
作者: Oh, Young-Taek Kim, Yong-Joon Lee, Jieun Kim, Myung-Soo Elber, Gershon Seoul Natl Univ Sch Engn & Comp Sci Seoul 151744 South Korea Chosun Univ Sch Comp Engn Kwangju 501759 South Korea Technion Israel Inst Technol Dept Comp Sci IL-32000 Haifa Israel
We present an efficient algorithm for projecting a continuously moving query point to a family of planar freeform curves. The algorithm is based on the one-sided Hausdorff distance from the trajectory curve (of the qu... 详细信息

Range Scan Registration Using Reduced Deformable Models
收藏 引用
COMPUTER GRAPHICS FORUM 2009年 第2期28卷 447-456页
作者: Chang, W. Zwicker, M. Univ Calif San Diego La Jolla CA 92093 USA Univ Bern Inst Informat & Angew Math CH-3012 Bern Switzerland
We present an unsupervised method for registering range scans of deforming, articulated shapes. The key idea is to model the motion of the underlying object using a reduced deformable model. We use a linear skinning m... 详细信息

A Skeleton-Based Approach for Consistent Segmentation Transfer
收藏 引用
JOURNAL OF INFORMATION SCIENCE AND ENGINEERING 2014年 第4期30卷 1053-1070页
作者: Wong, Sai-Keung Yang, Jau-An Ho, Tan-Chi Chuang, Jung-Hong Natl Chiao Tung Univ Dept Comp Sci Hsinchu 300 Taiwan
We present a skeleton-based approach for mapping consistently a segmentation of a source mesh to a target mesh. The source and target meshes are semantically similar but their geometries may be different. We assume th... 详细信息

Universal Reconfiguration of Facet-Connected Modular Robots by Pivots: The O(1) Musketeers
收藏 引用
ALGORITHMICA 2021年 第5期83卷 1316-1351页
作者: Akitaya, Hugo A. Arkin, Esther M. Damian, Mirela Demaine, Erik D. Dujmovic, Vida Flatland, Robin Korman, Matias Palop, Belen Parada, Irene Renssen, Andre van Sacristan, Vera Carleton Univ Ottawa ON Canada SUNY Stony Brook Stony Brook NY 11794 USA Villanova Univ Villanova PA 19085 USA MIT 77 Massachusetts Ave Cambridge MA 02139 USA Univ Ottawa Ottawa ON Canada Siena Coll Loudonville NY USA Tufts Univ Medford MA 02155 USA Univ Valladolid Valladolid Spain TU Eindhoven Eindhoven Netherlands Univ Sydney Sydney NSW Australia Univ Politecn Cataluna Barcelona Spain
We present the first universal reconfiguration algorithm for transforming a modular robot between any two facet-connected square-grid configurations using pivot moves. More precisely, we show that five extra "hel... 详细信息

Filtering Relocations on a Delaunay Triangulation
收藏 引用
COMPUTER GRAPHICS FORUM 2009年 第5期28卷 1465-1474页
作者: de Castro, Pedro Machado Manhaes Tournois, Jane Alliez, Pierre Devillers, Olivier INRIA Sophia Antipolis Mediterranee France
Updating a Delaunay triangulation when its vertices move is a bottleneck in several domains of application. Rebuilding the whole triangulation front scratch is surprisingly a very viable option compared to relocating ... 详细信息
