Summary (full chapter read)

Point-light shadows via cube (or dual-paraboloid) shadow maps vs stencil volumes. Dual-paraboloid = 2 passes vs 6 cube faces; filtering/packing tradeoffs. Softening via PCF-like filtering. Works with skinned/tessellated geometry. STALKER later treated omni as six spots for filtering (Gems2 Ch9).
