Design of a Walkthrough System for Virtual Museum Based on Voronoi Diagram
Found in: International Symposium on Voronoi Diagrams in Science and Engineering
By Lu Wang, Chenglei Yang, Meng Qi, Rui Wang, Xiangxu Meng, Xiaoting Wang
Issue Date:July 2006
pp. 258-263
This paper describes an integrated solution of designing a walkthrough system for virtual museum supporting multi-user's communion and learning based on Voronoi diagram. Here, 2D polygon and its Voronoi Diagram are the basis of museum?s cooperative design,...
Digital media service oriented digital museum Grid
Found in: International Conference on Computer Supported Cooperative Work in Design
By Rui Wang, Xiangxu Meng, Shijun Liu, Hai Guo, Chenglei Yang
Issue Date:April 2009
pp. 325-330
In this paper we design and implement a digital media service oriented digital museum platform based on Grid. We construct the whole system based on the Open Grid Service Architecture (OGSA), which supports flexibly constructing and deploying various digit...
Creating Cylindrical Panoramic Mosaic from a Pipeline Video
Found in: Computer-Aided Design and Computer Graphics, International Conference on
By Chuan Niu,Fan Zhong,Songhua Xu,Chenglei Yang,Xueying Qin
Issue Date:September 2011
pp. 171-175
In geological engineering, stratum structure detection is a fundamental problem in project planning and implementation. One of the most commonly employed detection technologies is to take videos of borehole using a forward moving camera. Following this app...
Voronoi-Based Potentially Visible Set and Visibility Query Algorithms
Found in: International Symposium on Voronoi Diagrams in Science and Engineering
By Lin Lu, Chenglei Yang, Weizhen Wang, Junqing Zhang
Issue Date:June 2011
pp. 234-240
In this paper, we propose the concept of Voronoi-based potentially visible set, called V\text underscore PVS, to facilitate the visibility computation. Given a polygon $P$, we first compute the Voronoi diagram of $P$, i.e., $\text{VD}(P)$. Then we refine $...
A BP Neural Network Prediction Model of the Urban Air Quality Based on Rough Set
Found in: International Conference on Natural Computation
By Zhifang Jiang, Xiangxu Meng, Chenglei Yang, Guansong Li
Issue Date:October 2008
pp. 362-370
The paper gives a BP neural network (BPNN) prediction model of the ambient air quality based on rough set theory. We make first the reduction of monitoring data of the pollution sources using the theory of rough set, extract the tidy rules. Then the topolo...
Automatically Approximating 3D Points with Co-Axisal Objects
Found in: Computational Science and its Applications, International Conference
By Russell Tempero, Sergey Bereg, Xiangxu Meng, Changhe Tu, Chenglei Yang, Binhai Zhu
Issue Date:July 2008
pp. 373-381
In this paper, we investigate the problem of approximating a set S of 3D points with co-axisal objects typically from CAD/CAM (namely, cylindrical segments, cones and conical frustums). The objective is to minimize the sume of volumes of these objects (as ...
New Intersection Algorithm of Convex Polygons Based on Voronoi Diagrams
Found in: International Symposium on Voronoi Diagrams in Science and Engineering
By Chenglei Yang, Pu Shi, Wei Zao, Lu Wang, Xiangxu Meng, Jiaye Wang
Issue Date:July 2006
pp. 224-231
A new fast and easy to implement tracing algorithm is presented for querying the intersection points of two convex polygons. We trace two edges to find the intersection points always along the boundaries of the union and intersection of P and Q respectivel...
The Design and Application of Agent on Pattern Cooperative Design Environment
Found in: Database and Expert Systems Applications, International Workshop on
By Chenglei Yang, Xiangxu Meng, Bin Gong, Changhe Tu, Zhenyu Teng
Issue Date:September 2000
pp. 753
Pattern design and print play an important role in the industry of printing and dyeing of chinaware, carpets etc. With the development of science and technology and the intensification of competition between corporations, it is necessary for corporations t...
