当大量查询point-location,并且arrangement频繁改变的时候,建议使用Arr_trapezoid_ric_point_location。 下面的代码是第一,第三种算法point-location示例 #include<CGAL/Exact_predicates_exact_constructions_kernel.h>#include<CGAL/Arr_non_caching_segment_traits_2.h>#include<CGAL/Arrangement_2.h>#include<vector>#...

step 1 - 将OpenMesh:TriMesh的mesh转化为CGAL:Surface_mesh<Point_3>的mesh step 2 - 将三个轴上的坐标转化成CGAL:Point step 3 - 调用PMP::locate() step 4 - CGAL:Face_location转化为OpenMesh:faceHandle remark : 输入的是OpenMesh类型的mesh,输出的是OpenMesh类型的FaceHandle,在过程中用到了CGAL的mesh。

Breaking change: The type of the result of point location queries has been changed to std::variant. Support for the old macro CGAL_ARR_POINT_LOCATION_VERSION has been removed. Breaking change: Eliminated the error-prone C-type casting that was used to define observers. In general, backward ...

The arrangement package has seen improvements for point location, rational functions and multi-part curves. It has also been extended with support for algebraic curves. This relies on several new packages that enable operations on (multivariate) polynomials and topology computation of such curves. ...
今天在工作中，发现我再调用外部API接口的时候，发现一个奇怪的问题，就是我Eclipse中写代码调用外部API接口时返回HTTP状态码是415，但是我将相同的报文放在HttpRequester里面请求的时候却又可以拿到正常返回结果，而不是415错误。
