Cgal projection

WebThe question is whether CGAL supports 2D Constrained Delaunay triangulation of 3D points using a projection onto an arbitrary plane? I know that it is possible for basic 2D Delaunay triangulation without constraints via Triangulation_2_filtered_projection_traits_3 as explained here.Is there anything like this for constrained case? Web我会试着把它推给CGAL。同时，您可以从下载它，并从下载一个使用示例。请注意，模块包含到xy平面的投影。如果您还需要投影到yz和zx平面，则需要复制类模板的代码 Arr_projection\u traits\u xy_3 ，并应用细微的更改。
