Maybe my description is not clear enough.  The location of each mesh is determined by its coordinates. So when cgal processes these meshes, does it default that the coordinates of these meshes are in the same coordinate system?

When adding a mesh, it is then considered as fixed (it should not be
modified). Its position in space is given by its coordinates.
When setting a transformation, it is done on the input mesh
even if a previous transformation was applied. If you want to
apply several transformation one after the other, you have to
update yourself the transformation accordingly.

I'm not sure to understand the question so let me know if I got it wrong.

Best,

Sebastien.

Dear all:
When I use the triangle meshes collision detection functions or
intersection detection functions:
https://doc.cgal.org/latest/Polygon_mesh_processing/classCGAL_1_1Rigid__triangle__mesh__collision__detection.html
<https://doc.cgal.org/latest/Polygon_mesh_processing/classCGAL_1_1Rigid__triangle__mesh__collision__detection.html>
https://doc.cgal.org/latest/Polygon_mesh_processing/group__PMP__predicates__grp.html
<https://doc.cgal.org/latest/Polygon_mesh_processing/group__PMP__predicates__grp.html>
to detect collisions, intersections and inclusions among input meshes.
Whether these methods have automatically converted these meshes to the
same coordinate？

* If not, how to judge the positional relationships of the meshes
under different coordinate systems.
* If so, in which method is the coordinate system transformation
encapsulated
