The 3D Object Reconstruction Algorithm for Scattered Points in Triangulation;

Tool-Path Planning of NC Machining Based on Scattered Points;

The boundary curve of the planar projected points of the measured scattered points had been extracted.

The inherent topologic relations between the scattered points on the curved surface are reconstructed by the weight vectors of the neurons on the output layer of the neural network.

Data preprocessing technique of scattered point cloud in reverse engineering;

Simplification of scattered point cloud with geometric feature reservation

The measurement of scattered point cloud data is the foundation of surface reconstruction of a 3D object.

A novel algorithm based on scanning step d for speeding up the process to find the all k nearest neighbors of scattered points was presented.

A new reduction algorithm for scattered points based on local surface feature was proposed.

This paper discussed the extension of the paving algorithm for all quadrilateral mesh generation to use scattered points as input instead of CAD model.

In order to extend the applicability of data processing and surface rendering on the VTK-based visualization platform,a new method is presented which can convert scattered points into the standard VTK data format.

An algorithm for curve reconstruction from unorganized points is presented.

The triangulation of unorganized points on a surface plays a important role for surface reconstruction.

This thesis centers on the issue of surface reconstruction in graph division, parameterization and construction from unorganized points, contour points and triangle meshes.
