摘　　要：在一个基于虚拟现实技术的系统中,当搭建好大致模型时,会发现所有物体可以相互穿透,例如人穿墙,人穿树等“诡异”事件发生且人物模型行走没有规划,不能沿着设置好的道路自动寻路且交互式漫游不能实现。为了避免这种在现实生活中不可能发生的情况,尽量提高虚拟现实系统的真实性,需要为物体添加防碰撞技术,并添加可以引导人物自动寻路的导航网格自动寻路技术,加之缸体加速、控位移动实现交互式漫游。另外,为提高人物灵活性,利用Mixamo创建人物模型,并导入模型制作软件为其绑定骨骼。实验结果表明:人物行走更为灵活,可自动寻路且不会出现碰撞事件发生,交互式漫游也可实现。In a virtual reality-based system,when a rough model it built,that all objects can penetrate each other will be founded.For example,events that people can wear walls,trees and other"singular"events occur.Automatic road routing with set up roads and interactive roaming cannot be achieved.In order to avoid such a situation that is impossible in real life,try to improve the authenticity of the virtual reality system needs to be improved,anti-collision technology is added to the object,and add a navi⁃gation grid automatic path finding technology that can guide the person to automatically find the path is added,the cylinder body ac⁃celeration and position control move for interactive roaming is plused.In addition to improving character flexibility,Mixamo is used to create a character model and import model creation software to bind bones.The experimental results show that the characters walk more flexibly,it can automatically find the way and there will be no collision events,and interactive roaming can also be realized.
