Example Embodiment
[0068] Please check Figure 1 to Figure 14 , an edge-by-edge layering method for a triangular patch model in rapid prototyping, which specifically includes the following steps:
[0069] Step 1, based on the triangular patch model data read into the memory, remove redundant points, and create a positive edge table and its left and right connection patch information;
[0070] like figure 2 As shown, the vertex structure POINT contains three floating-point variables for saving the three-dimensional coordinates of the vertex, and the face structure FACET contains an integer variable array with a length of 3. Use the sequence container vector class in the C++ standard template library to declare the point table vector m_vecPoints and declaration patch table vector m_vecFacets. When reading the triangular patch model, such as the STL model, from the hard disk into the memory, the associative container classes in the C++ standard template library, such as set, map, multimap, etc...
