Surface Points Quick Pick-up Technology of STL Format Models

The STL Format Product Models (STL Models for short) comprise thousands of adjacent triangular faces. As a result of the complexity and variety of STL triangular faces, the operation of surface points pick-up needs a relatively long time. This causes great inconvenience for users to manipulate STL Models. To solve this problem, this paper analyzes the surface points quick pick-up principles of STL models, comes up with a points quick pick-up algorithm, and gives an algorithm application and it’s results.
