This　paper　presents　a　real-time　rendering　method　based　on　the　GPU　programmable　pipeline　for　rendering　the　3D　scene　in　ink　wash　painting　style.　The　method　is　divided　into　main　three　parts:　First,　render　the　ink　properties　of　3D　model　by　calculating　its　vertex　curvature.　Then,　cached　the　ink　properties　to　a　paper　structure　and　using　an　ink　dispersion　model　which　is　defined　by　referencing　the　theory　of　porous　media　to　simulate　the　dispersion　of　ink.　Finally,　convert　the　ink　properties　to　the　pixel　color　information　and　render　it　to　the　screen.　This　method　has　a　better　performance　than　previous　methods　in　visual　quality.
