摘要：The need for ways to obtain highly accurate 3D shape data from existing 2D contours is increasingly necessary in some applications, such as in disaster prevention, environmental analysis, and creating construction plans. In this paper, we propose an algorithm that reconstructs a curve mesh model of mountain with triangular and quadrilateral domains that is generated from discrete contours data by using constrained Delaunay triangulation method. To prove the effectiveness of our method, we interpolated the curve mesh into free-form surface model with G ¹ continuity and compared the accuracy and quantity of data with other methods.
