介绍了一种三角曲面的构建方法,首先以三条边和其中一条边对应的顶角创建三角曲面;接着在顶角收敛处创建投影曲线,并用投影曲线将收敛的部分曲面裁剪掉;然后以四条边界曲线创建曲面,并使曲面和原曲面相切;最后合并两曲面。通过曲面偏距网格分析可知,曲面的U、V方向网格线不再相交于一点,表明曲面品质在收敛角处得到改善。
介紹瞭一種三角麯麵的構建方法,首先以三條邊和其中一條邊對應的頂角創建三角麯麵;接著在頂角收斂處創建投影麯線,併用投影麯線將收斂的部分麯麵裁剪掉;然後以四條邊界麯線創建麯麵,併使麯麵和原麯麵相切;最後閤併兩麯麵。通過麯麵偏距網格分析可知,麯麵的U、V方嚮網格線不再相交于一點,錶明麯麵品質在收斂角處得到改善。

This paper introduces the construction of triangular curved surface, that a triangular curved surface is created with three sides and corres ponding vertex angle of one side, then a projection curve is set up at the convergence of the vertex angle and partial converged surface is cut out with the projection curve. Then a curved surface is establised with the four boundary curves, which is made tangential to the original one. Final y the two curved surfaces are merged. Through the curved surface offset grid analysis, it is lound that the surface U, V direction grid lines never intersect at one point. This shows that the surface quality gets improved at the converged angle.
