基于图像的图形绘制技术的应用

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ACTIVEX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，实用了在Internet网上进行虚拟环境漫游的功能。

AN APPLICATION OF IMAGE- BASED RENDERING TECHNOLOGY

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.
