摘要：

为了解决三维造型中的曲面拼接问题,提出基于空间趋向曲线的网格曲面拼接方法.该方法有效地结合边界曲面的延伸信息,简单高效地构造光滑的过渡曲面；通过对两待拼接曲面边界点参数归一化,由参数聚类,建立曲面边界之间的匹配点对关系；在每对匹配点对之间构建由Bézier表征的空间趋向曲线,使空间曲线在对应点对上与待拼接曲面保持二阶连续；对空间趋向曲线族进行离散化和三角化,得到光滑的过渡曲面.结果表明,与其他传统方法比较,该方法在曲面拼接应用中具有高效可靠的优势.
Abstract:

To solve surface stitching problem in 3D modeling, we proposed a method of spatial-trend-curve based mesh surface stitching. The method effectively combined potential extension information of boundary to simply and efficiently construct smooth transitional surface: the corresponding-point-pairs between two boundaries of the separated surface were matched by parametric normalization and clustering; a spatial-trend-curve represented by Bézier-curve with second-order continuity was generated on each pair of corresponding points; a smooth transitional surface was finally obtained by sampling and skinning the spatial-trend-curves. Results shows that our method have the advantage of high efficiency and reliability compared with other traditional methods．
