Volumetric data modeling and analysis based on seven-directional box spline

Science China(Information Sciences) 2014年第6期57卷 260-273页

作者： FANG MeiE LU Jia PENG QunSheng School of Computer Science and technology Hangzhou Dianzi University State Key Lab of CAD&CG Zhejiang University

The existing methods for visualizing volumetric data are mostly based on piecewise linear models.And all kinds of analysis based on them have to be substituted by coarse interpolations.So both accuracy and reliability of the traditional framework for visualization and analysis of volumetric data are far from our needs of digging information implied in volumetric data fields.In this paper,we propose a novel framework based on a C2-continuous seven-directional box spline,under which reconstruction is of high accuracy and differential computations relative to analysis based on the reconstruction model are accurate.We introduce a polynomial differential operator to improve the reconstruction accuracy.In order to settle the difficulty of evaluating upon the seven-directional box spline,we convert it into B′ezier form and propose effective theories and algorithms of extracting iso-surfaces,critical points and curvatures.Plentiful of examples are also given in this paper to illustrate that the novel framework is suitable for analysis,the improved reconstruction method has high accuracy,and our algorithms are fast and stable.

Element-Partition-Based Methods for Visualization of 3D Unstructured Grid Data

引用

Journal of Computer Science & Technology 1998年第5期13卷 417-425页

作者：武君胜吴广茂 Aeronautics Computing Technique Research Inst Xi'an China

E lement- partition- based methods for visualization of 3D unstructured grid data are presented. First, partition schemes for common elements, including curvilinear tetrahedra, pentahedra, hexahedra, etc., are given, so that complex elements can be divided into several rectilinear tetrahedra, and the visualization processes can be simplified.Then, a slice method for cloud map and an iso-surface method based on the partition schemes are described.
