topological triangle meaning in Chinese

拓扑三角形

but a single b-spline surface can only represent rectangular topology type in essence . it is really a hard work that to generate smooth b-spline surfaces from arbitrary topological triangle meshes
但由于b样条曲面只能表示矩形拓扑的数据，所以将任意拓扑的三角网格数据转换为b样条曲面表示是一个比较困难的研究课题。
here two different methods of reconstructing b-spline surfaces from arbitrary topological triangle meshes are proposed, namely one method based on catmull-clark subdivision and the other based on partitioning and resampling . if smaller patches are required, the method based on catmull-clark subdivision is presented
在本文中，主要基于两种不同的应用角度探讨了如何将任意拓扑的三角网格数据转换为b样条曲面表示：基于catmull-clark子剖分的曲面生成与基于分割与重采样的大片b样条曲面生成。
