In　order　to　better　understand　the　wind　affects　the　tree　architecture　deformation　intuitively,　an　efficient　modeling　strategy　of　virtual　tree　swaying　in　wind　was　proposed　based　on　the　analysis　of　the　existing　thought　and　methods　to　simulate　the　tree　movement　in　wind.　The　method　used　procedure　function　with　stochastic　factor　to　simulate　the　wind　field;　and　the　cantilever　beam　was　used　to　simulate　a　segment　of　a　stem　as　the　mechanical　analysis　unit,　the　deformation　of　the　beam　in　wind　force　based　on　the　theory　of　wind　projection　and　beam　element　was　computed.　Then　the　force　transmission　and　movement　compounding　method　was　used　to　solve　the　whole　tree　movement　in　wind.　Furthermore,　some　software　function　modules,　which　integrated　with　the　parametric　tree　modeling　prototype　system,　were　developed.　Taking　Phyllostachys　pubescens　as　an　example,　the　tree　swaying　was　simulated　in　different　wind　velocities　and　with　different　modulus　of　elasticity.　The　result　is　in　accordance　with　the　practical　visual　effects.
