Research on Compression Methods for ASCII STL File

Abstract:

Article Preview

Two new types of ASCII format STL file are presented under lossless data compression and lossy implicit data compression respectively. In these new format file, a vertex with three coordinates which has degree n is stored only once rather than n times and three vertexes of a facet are saved by their indexes instead of by their three coordinates (x, y, z). As a result, the storage space of the vertex reduces to about 1/3 of its original space. It is very convenience for the file transmitting of network manufacturing. Moreover, the reading, writing and pretreatment time of data file are shortened greatly because of the decreasing of the file length.
