Research on the Simplification of STL Model

STL模型的某些区域存在一些狭长的钝角三角形,它们对模型逼近误差的影响非常小,在精度允许的条件下可以将其忽略。通过剔除部分符合一定条件的钝角三角形,合理简化了STL模型,节省了文件存储空间和后续数据处理时间。

There are some long and narrow obtuse triangles existing in certain area of STL model, and they have little impact on approaching error of the model, even can be ignored if accuracy permits. Through eliminating some obtuse triangles, STL models were reasonably simplified, the time of subsequent data processing and the storage space for STL file were saved.
