目前unity3D游戲引擎已經(jīng)廣泛的用于游戲開發(fā)，而且unity3d在國(guó)內(nèi)發(fā)展比較迅速，已經(jīng)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(wǎng)絡(luò)上unity3D的中文學(xué)習(xí)資料也逐漸豐富。為了方便客戶使用wiseglove數(shù)據(jù)手套，我們專門組織編寫了在Unity3D環(huán)境下調(diào)用wiseglove數(shù)據(jù)手套SDK開發(fā)包，用數(shù)據(jù)手套的實(shí)時(shí)數(shù)據(jù)來驅(qū)動(dòng)unity3d中的角色右手模型的demo程序。

Unity3D的新版動(dòng)畫系統(tǒng)Mecanim已經(jīng)對(duì)人類類型的角色支援設(shè)計(jì)了一套殊的工作流程。用戶將3dsmax或者maya中導(dǎo)入的人形角色導(dǎo)入unity3d后，需要為角色創(chuàng)建Avatar，本質(zhì)上就是分析導(dǎo)入資源的骨骼結(jié)構(gòu)，并對(duì)其進(jìn)行標(biāo)識(shí)，從而轉(zhuǎn)化成Mecanim可以識(shí)別的骨骼結(jié)構(gòu)，或者說轉(zhuǎn)化成通用的骨骼結(jié)構(gòu)，這也是為什么在資源準(zhǔn)備時(shí)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(duì)骨骼的識(shí)別。

在導(dǎo)入的資源都具有通用的骨骼結(jié)構(gòu)時(shí)，就可以實(shí)現(xiàn)動(dòng)畫的共用。

在這里我們用wiseGlove數(shù)據(jù)手套驅(qū)動(dòng)右手模型時(shí)也使用了unity標(biāo)準(zhǔn)的avatar映射的人手關(guān)節(jié)模型，這樣方便我們對(duì)不同的角色的右手模型進(jìn)行驅(qū)動(dòng)。

下面是用于驅(qū)動(dòng)人手模型的代碼，需要將這段代碼掛載在場(chǎng)景中的角色身上：
