In　this　paper,　we　present　an　adaptive　particle　shape　setting　method　in　Lagrangian-approach　based　screen　space　splatting　algorithm　in　real-time　fluid　rendering.　The　particle　radius　will　be　adjusted　according　to　its　Weber　number　and　local　density　in　the　rendering　process　so　that　a　large　radius　of　peaceful　fluid　particle　can　help　to　eliminate　a　bumpy　surface　artifact,　and　a　small　radius　can　prevent　the　obviously　spherical　shape　of　particles　in　splash.　The　shape　of　fluid　particle　will　be　controlled　adaptively　on　the　basis　of　Weber　number　too,　so　that　fast　moving　particles　could　have　an　ellipsoidal　appearance　which　describes　the　splash　particle　shape　in　turbulent　flow　persuasively.　We　also　propose　an　adaptive　normal　calculation　method　to　avoid　the　numerical　calculation　errors　in　the　normal　computation　process.　The　sampling　interval　will　be　set　in　accordance　with　the　viewing　distance　from　camera　to　the　fluid　so　that　fuzzy　edges　or　double　image　effect　in　a　fixed　sampling　interval　normal　computation　process　could　be　prevented.　Both　of　the　two　approaches　introduced　in　this　paper　take　only　small　amount　of　computing　time　and　will　have　little　impact　on　the　time　consuming　property　of　a　real-time　fluid　rendering　application.
