Compute $ y += alpha T_t(x) $ , where $ T_t $ is the translation operator $ T_t(x(r)) = x(r+t) $ modulo the lattice vectors T must conserve integral(x) and satisfy $T^{\dagger}_t = T_{-t}$ exactly for gradient correctness Note that $T^{-1}_t = T_{-t}$ may only be approximately true for some implementations.
