In　order　to　render　realistic　human　face　with　fine　skin　structure,　we　present　a　novel　method　based　on　bump　mapping.　First　of　all,　we　project　the　normal　map　on　facial　model　for　each　pixel　of　normal　map　represents　a　normal　vector.　Therefore,　there　are　pixel-level　normal　vectors　on　the　surface　of　facial　model.　Then,　we　disturb　the　normal　vector　using　light　vector　and　combine　the　result　with　facial　color　texture　as　color　texture.　Finally,　we　render　the　facial　model　with　realistic　textured　skin　and　accidental　characteristic.
