Importance-Driven Isosurface Decimation for Visualization of Large Simulation Data Based on OpenCL
Found in: Computing in Science & Engineering
By Yi Peng,Li Chen,Jun-Hai Yong
Issue Date:January 2014
pp. 24-32
A new way to define mesh importance for decimation uses transfer functions and visualizes large simulation data in cases where normal visualization methods are insufficient due to memory limit. Next, a parallel isosurface simplification framework uses pyra...
The Transition Between Sharp and Rounded Features and the Manipulation of Incompatible Boundary in Filling n-sided Holes
Found in: Shape Modeling and Applications, International Conference on
By Kan-Le Shi, Jun-Hai Yong, Peng Liu, Jia-Guang Sun, Jean-Claude Paul
Issue Date:June 2010
pp. 131-142
N-sided hole filling plays an important role in vertex blending. Piegl and Tiller presented an algorithm to interpolate the given boundary and cross-boundary derivatives in B-spline form. To deal with the incompatible cases that their algorithm cannot hand...
A Face-Based Shape Matching Method for IGES Surface Model
Found in: Shape Modeling and Applications, International Conference on
By Kai-Mo Hu, Bin Wang, Yi Gao, Qi-Ming Yuan, Jun-Hai Yong
Issue Date:June 2010
pp. 216-220
IGES is a widely used standard for mechanical data exchange. In this paper, we present a new method for the retrieval task of IGES surface model. Based on this method, a novel distinctive face selection strategy is proposed and evaluated. In the training d...
A Fast Sweeping Method for Computing Geodesics on Triangular Manifolds
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Song-Gang Xu, Yun-Xiang Zhang, Jun-Hai Yong
Issue Date:February 2010
pp. 231-241
A wide range of applications in computer intelligence and computer graphics require computing geodesics accurately and efficiently. The fast marching method (FMM) is widely used to solve this problem, of which the complexity is O(N\log N), where N is the t...
Mesh Parameterization for an Open Connected Surface without Partition
Found in: Computer Aided Design and Computer Graphics, International Conference on
By Yu-Shen Liu, Pi-Qiang Yu, Ming-Cui Du, Jun-Hai Yong, Hui Zhang, Jean-Claude Paul
Issue Date:December 2005
pp. 306-312
A novel mesh parametrization method for an open connected surface is presented. The parametrization method is based on Hessian-based Locally Linear Embedding (HLLE). Our method operates directly on the surface without using any partition technique and can ...
A framework for seamless computer supported cooperative work in three-dimensional design
Found in: International Conference on Computer Supported Cooperative Work in Design
By Jun-Hai Yong
Issue Date:May 2005
pp. 638-642 Vol. 1
A framework for computer supported cooperative design is proposed in this paper. With the system customization, the cooperation could be seamless. Namely, cooperation conflictions are detected automatically, and the designers are able to customize the syst...
Towards Photo Watercolorization with Artistic Verisimilitude
Found in: IEEE Transactions on Visualization and Computer Graphics
By Miaoyi Wang,Bin Wang,Yun Fei,Kanglai Qian,Wenping Wang,Jiating Chen,Jun-Hai Yong
Issue Date:February 2014
pp. 1
We present a novel artistic-verisimilitude driven system for watercolor rendering of images and photos. Our system achieves realistic simulation of a set of important characteristics of watercolor paintings that have not been well implemented before. Speci...
Bilateral blue noise sampling
Found in: ACM Transactions on Graphics (TOG)
By Huamin Wang, Jun-Hai Yong, Li-Yi Wei, Wenping Wang, Yun Fei, Bin Wang, Jiating Chen, Kang-Lai Qian, Xiaoyin Ge, Yusu Wang
Issue Date:November 2013
pp. 1-11
Blue noise sampling is an important component in many graphics applications, but existing techniques consider mainly the spatial positions of samples, making them less effective when handling problems with non-spatial features. Examples include biological ...
