摘　　要：针对视景仿真中视点跟随技术开发的难点,详细分析了物理模型运动的矩阵计算原理,利用OSG三维渲染开源平台,借助船舶驾驶航行系统实现了两种第一人称漫游,即视点跟随键盘响应事件与视点和跟随节点的完全联动.重点介绍了视点跟随完全联动原理,指出此视点跟随方法更加接近真实世界,此第一人称视点跟随效果,包括无风浪情况和有风浪情况的视点跟随,使得此项技术应用范围拓展到几乎所有的仿真视景漫游程序的开发中.For visual simulation with technology development in the difficulty of viewpoint,it analyzed the physical model of matrix calculation principle,motion using OSG（OpenSceneGraph） 3d rendering open-source platform,with ship＇s navigation system realizes the two first-person roaming effect.It realized with keyboard response events and point of view and completely linkage follow node two visual effects.Mainly introduces viewpoint,this principle with completely linkage with methods closer to the real point of the world,through the results observation,the successful implementation of the first person perspective follow effects,including no waves and the wind conditions,make the technology with viewpoint application scope extend to almost all of the simulation visual roaming program development.
