摘　　要：插值由特征曲线组成的曲线网是最常用的曲面建模思路,而从简单矩形拓扑曲线网到任意拓扑曲线网的扩展不仅增强了曲面设计自由度,而且提高了曲面设计效率。以曲线网建模过程为序,介绍了任意拓扑曲线网的创建和编辑、插值曲面的构造以及曲线网建模系统研究等技术的研究现状,分析了Bezier和NURBS曲面、Gregory曲面片和细分曲面在曲线网插值中的应用特点,指出了今后研究的重点。Building surface from curve network formed by characteristic curve is the most common modeling method.The extension from rectangle domain of curve network to arbitrary topological curve network provides more freedom degree and higher efficiency for designer.The present situation of constructing and modifying arbitrary curve network and generation and the system of curve networks modeling are introduced in sequence of curve network modeling.The features of general parameter surface,Gregory patch and subdivision surface on curve network interpolation are analyzed emphatically and the development tendency is predicted.
