摘　　要：本文对基于图像的图形绘制技术的特点及理论基础进行了简要介绍,并采用柱面全景图的方法设计、实现了一个基于图像的图形绘制技术的应用系统。该系统提供了全景图生成工具,能自动生成给定视点的全景图;采用独到的加速算法,满足了人-机交互所要求的实时性;采用ACTIVE X控件形式封装整个系统,与Internet浏览器相结合,增加了全景图浏览器的网络功能,实现了在Internet网上进行虚拟环境漫游的功能。In the first place of this paper, the characteristics and the theoretical basis of image - based rendering technology are introduced in brief. We have further expatiated on the method of cylinder panorama,and as a result, we have implemented an application system.It is provided with the following capabilities: a tool of establishing a cylinder panorama, adopting a unique algorithm to speed up the cylinder inverse transform, and a panorama browser with network function. Because of these fast algorithms, we have attained our goal that the virtual reality system is necessary to be a real- time one.
