自主非玩家角色面部行为的实现

为了用自主非玩家角色（ANPC）来实现游戏里的人工智能，提出了一种“模型．视图．控制器（VC），的设计模式来实现此类ANPC，该模式将AI从游戏引擎中分离出来。用一种混合变形顶点着色（BMVS）技术实现ANPC的面部行为，该技术可以把各个行为动画，如眨眼、微笑、视位（visemes），混合形成整个面部行为动画。采用顶点着色技术，不用锁定顶点缓存和新建混合后形成的网格（mesh），因而能提高动画渲染效率。

Implementation of facial behavior for autonomous nonplayer characters

Autonomous nonplayer characters(ANPC) are proposed to apply in game AI,therefore the model-view-controller(MVC) design pattern is used to separate AI from game engine.Facial behavior for ANPC is implemented by blending morph vertex shader(BMVS) technique in which the meshes of previously created animations,such as blinking,smile and visemes,can be blended to form new and unique animations on the fly and in real time.It's all happening in line with the vertex shader,no more locking and rebuilding a morphing mesh each frame.
