Abstract: | In this paper, we present an algorithm for the reconstruction of piecewise linear surfaces from unorganized sample points with an improved -shape. Alpha-shape provides a nice mathematical definition of the shape of a set of points, but the selection of an value is tricky in surface reconstruction. F or solving this problem and the non-uniform distribution, we scale the ball according to the points density. The method discussed in this paper might be applied for surface reconstruction, and the process is fully automatic. |
