 The current implementation of the computation of the SDF values relies on the \ref PkgAABB_treeSummary package.
 This operation is reliable when the `AABBTraits` model provided has exact predicates.
+`::CGAL::Exact_predicates_inexact_constructions_kernel` is recommended as geometric traits for this algorithm.
