摘　　要：传统B样条曲面拼接要求在拼接边界上节点矢量相同,导致使用范围受限。提出一种适用于节点矢量不必相同的曲面拼接方法,可在一张曲面因几何约束而发生形状改变后,其他与之相接的曲面自适应地做出变形调整,保证精度要求下的拼接边界G^1连续,并运用实例验证了多曲面拼接方法的有效性。Traditional B-spline surface stitching needs the same node vector on the splicing boundary,thus limiting the useful range.This paper proposes a surface splicing method which has no need for the same node vectors.After a shape changes according to the geometric constraints,other curved surfaces neighbored can be adaptively adjusted to ensure G 1 continuity at the boundary,and the effectiveness of the multi-surface stitching method is verified by an example.
