基于Vega的油库虚拟漫游系统视点运动模型的实现

Implementation of Observer Motion Model in Vega-based Oil Tanks Virtual System

视点运动模型是视点的一组运动约束,它描述和限制了视点的运动方式。Vega软件中提供了多种视点运动模型。主要研究在Vega提供的按路径运动的视点运动模型基础上,如何实现对视角的控制。在油库虚拟漫游系统中实现了按路径运动且视角可控的视点运动,结果表明该方法简便有效,增强了系统的交互性。

Observer is a group of motion restrictions of observer which describes and restricts the moving way of the observer.Vega can offer several motion models moving around the scene for user.This paper mainly introduces the implementation of the observer position which can be controlled through programming.We use the method to establish the virtual wandering system of a gas station.The results show that the operation is easy and effective,and the interaction of the system is improved efficaciously.
