In fact I am wrong and what Maxime proposed deals with positional tests.

Hello,

lso have a look at the simpler functions

As you speak about positional, the above as well as what Maxime gave you
will not tell you that a cube is contained in another one.

For that have a look at

https://doc.cgal.org/latest/Polygon_mesh_processing/classCGAL_1_1Side__of__triangle__mesh.html

best,

Hi,

You can have a look at this function : https://doc.cgal.org/latest/Polygon_mesh_processing/classCGAL_1_1Rigid__triangle__mesh__collision__detection.html

It allows you to detect collisions, intersections and inclusions between meshes.

Dear developers and users,

I am a newbie of CGAL, now  I want to use the CGAL library to judge the positional relationship of some regular 3D polyhedras (similar to cubes and cuboids), such as judging whether two polyhedra intersect (or whether there is a "collision" between two geometric bodies), therefore, I would like to know which package in the CGAL library should I understand that enables me to detect collisions of 3D polyhedrons.

Thanks for your help.
