Paper Title:
The Method for the Accuracy Improvement of STL Offset Model Based on Vertex Offset
  Abstract

On the basis of the analysis for the reason that causes the errors of the vertex offset, the accuracy improvement method for the STL offset model which was generated by the vertex offset algorithm was proposed by using the surface subdivision algorithm based on the center of gravity on triangular facets. The offset point of the center of gravity was generated by offset the center of gravity along the normal vectors of the triangular facets on which the center of gravity is located, and the new triangular facets are formed by connecting the offset points of the center of gravity and the offset vertexes of the triangular facets so that the more accurate offset model to be built. The case study shows that the proposed algorithm has higher accuracy than the existing vertex offset algorithm.
