A Simple 3-D Surface Reconstruction Method

3-D surface reconstruction based on contour maps is a current research focus. However, to read contour maps requires some professional knowledge and to reconstruct 3-D surface with contour maps needs professional tools such as OpenGL and high programming capabilities. This paper presents an algorithm of 3-D surface reconstruction based on scattered points. First, the algorithm triangulates with these scattered points in plane and segments each triangle to get some interior points, then calculates the coordinate of each point as well as its elevation. Last, the algorithm triangulates with all the points and generates triangular patches in 3-D space. The experiment result and complexity analysis of the algorithm show that the algorithm is simple and easy to achieve expected results.
