Neither. It stores them as points in a 3 dimensional lookup structure
independent of any objects in the scene but also independent of viewing
angle. In Jensen's case, he uses a kd-tree. Actually, Jensen has at
least three papers that apply to photon mapping. All but his SIGGRAPH
'98 paper are on his website, and if you email him he'll send you the
URL for that one.
