You need to construct the affine transformation.
https://doc.cgal.org/latest/Kernel_23/classCGAL_1_1Aff__transformation__3.html
Examples:
typedef Kernel::Aff_transformation_3 Trsfrm;
// scaling
PMP::transform(Trsfrm(CGAL::SCALING, 0.5), mesh);
// translation
double dx, dy, dz;
PMP::transform(Trsfrm(CGAL::TRANSLATION, Kernel::Vector_3(dx, dy, dz)), mesh);
Best,
Sebastien.

Hi all,
Does anyone know of an example of using the transform function to move a polygon mesh? (say, by an offset consisting of 3 floats to move a mesh in 3D space) The PMP examples don't have one afaics.
Giles.
