摘要
运用散列的方法重建STL文件的拓扑信息,并充分利用拓扑信息对STL文件的常见错误进行修复。研究了拓扑重建过程中散列Key值的计算方法,常见错误与拓扑信息的关联,修复错误的方法与流程。对于STL这种大数据量的文件,利用散列可以大量减少计算量,尤其对于拓扑重建的工作可以做到非常高效。本文为关于STL的错误修复与其他处理提供了一种高效的方法。
Topological reconstruction and errors repair of an STL model using hashing is addressed in this paper. The main contents are： a method for calculating the key value of hashing during topological reconstruction, common errors and their relationship between topological structures of mesh, a method and procedure for repairing errors. Using hashing can reduce much computing work, especially for the reconstruction of STL model. This paper offers an effective method for error repairing and the processing of an STL file.
