目前unity3D游戲引擎已經廣泛的用于游戲開發(fā)，而且unity3d在國內發(fā)展比較迅速，已經成為了主流的游戲開發(fā)引擎之一。隨著越來越多的開發(fā)人員開始使用unity3D，網絡上unity3D的中文學習資料也逐漸豐富。為了方便客戶使用wiseglove數據手套，我們專門組織編寫了在Unity3D環(huán)境下調用wiseglove數據手套SDK開發(fā)包，用數據手套的實時數據來驅動unity3d中的角色右手模型的demo程序。

Unity3D的新版動畫系統(tǒng)Mecanim已經對人類類型的角色支援設計了一套特殊的工作流程。用戶將3dsmax或者maya中導入的人形角色導入unity3d后，需要為角色創(chuàng)建Avatar，本質上就是分析導入資源的骨骼結構，并對其進行標識，從而轉化成Mecanim可以識別的骨骼結構，或者說轉化成通用的骨骼結構，這也是為什么在資源準備時在骨骼的創(chuàng)建及命名要遵循一定的規(guī)范的原因，這樣方便mecanim對骨骼的識別。

在導入的資源都具有通用的骨骼結構時，就可以實現動畫的共用。

在這里我們用wiseGlove數據手套驅動右手模型時也使用了unity標準的avatar映射的人手關節(jié)模型，這樣方便我們對不同的角色的右手模型進行驅動。

下面是用于驅動人手模型的代碼，需要將這段代碼掛載在場景中的角色身上：
