Constraint-based solid modeling is the kel part of current CAD systems. It has been widely used in supporting detailed design and variational design. However, i...
[期刊论文] 作者:FAN HanQi,PENG QunSheng,YU YiZhou,, 来源:Science China(Information Sciences) 年份:2013
Finely captured meshes often contain details like sharp edges, corners and shallow features. In order to improve the quality of these meshes, we present a robus...
[期刊论文] 作者:FANG MeiE,LU Jia,PENG QunSheng,, 来源:Science China(Information Sciences) 年份:2014
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 accurac...
