  The three-dimensional femtoscopic correlations of pions and kaons are
presented for Pb$-$Pb collisions at \rootsNN = 5.02 TeV within the framework of
  (3+1)D viscous hydrodynamics combined with THERMINATOR 2 code for statistical
hadronization. The femtoscopic radii for pions and kaons are obtained as a
function of pair transverse momentum and centrality in all three pair
directions. The radii showed a decreasing trend with an increase of pair
transverse momentum and transverse mass for all centralities. These
observations indicate the presence of strong collectivity. A simple effective
scaling of radii with pair transverse mass was observed for both pion and
kaons.
