摘　　要：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。This paper introduces the construction of triangular curved surface, that a triangular curved surface is created with three sides and corresponding 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. Finally the two curved surfaces are merged. Through the curved surface offset grid analysis, it is Iound 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.
