基于Virtools的视点控制功能设计与应用

Design and Application of Viewpoint-control Function Based on Virtools

视点控制是虚拟现实的关键技术之一。本文基于虚拟开发工具Virtools对虚拟场景中的常用视点控制功能进行了设计,通过鼠标和键盘对摄像机的控制,实现了自动漫游、第一人称视角、试点切换、视点跟随等功能,具有较好的可移植性和再开发性,并将其运用于某室内漫游系统设计中。

viewpoint-control is one of the key technologies of virtual reality.In this article,some commonly used functions of viewpoint control was designed based on the development tool Virtools,through the control of the camera by mouse and keyboard,realized functions like automatic roaming,first person perspective,viewpoint switch,viewpoint following and so on,the proposed functions were grealty transplantable and re—developable and were used in the roaming system of an room.
