Description:
Cocone software can reconstruct a surface from its sample points. The input is the coordinates of the point cloud in 3D and output is a piecewise linear approximation of the surface which is made of Delaunay triangles with vertices in the input points only. The software is based on the cocone algorithm that uses a single Voronoi/Delaunay computation. The program works on the assumption that the sample is dense and is obtained from a smooth surface. We have four versions of the software catering different needs. In addition to the surface, Tight Cocone below can compute an approximate medial axis or MAT of the object. Codes are available for Irix-6.4, Linux-2.4.-i386, Solaris-5.6-sparc and Windows. Please send an email to tamaldey@cse.ohio-state.edu to get the password to access the download area. (Mention the code name(s) from the list below for which download is requested). 1. Tight Cocone: This produces a Water Tight model no matter how the input is (implemented by Samrat Goswami). It also computes the medial axis (implemented by Wulue Zhao). 2. Cocone: This detects Boundaries in the surface. Thus, this version is suitable for reconstructing surfaces that have boundaries. Notice that it will also detect regions of undersampling. (implemented by Joachim Giesen.) 3. SuperCocone: This handles very Large data sets. For example, it can handle data sets in the range of million points. (3.5 million points on a 733Mhz, 512MB memory machine takes 3hrs and 18 minutes). (implemented by James Hudson). 4. RobustCocone: This handles noisy data sets. If the input points are noisy, this reconstructs a surface interpolating through a subset of the points (implemented by Samrat Goswami). RobustCocone does not smooth data. It interpolates the data. For smoothing noisy point clouds use AMLS software.
