摘要
随着计算机技术的发展,特别是三维计算机立体图形绘制、显示技术的发展,使逼真地、立体地重现自然成为可能。现在立体显示技术已广泛应用于医学图象、应用科学、可视化工程、虚拟现实和模拟训练教育等方面。确定正确的立体图象投影模型是利用计算机产生逼真图象的关键技术之一,本文介绍了计算机立体显示基本原理及立体观察的几何模型并概述了影响计算机立体图象绘制和显示的几个重要因素。
With the development of the computer technique especially the 3D stereoscopic computer graphics rendering and display technique,it is probable to rebuild stereo nature realistically. Nowadays the stereoscopic display technology is already benefiting many applications including medical imaging,scientific and engineering visualization, virtual reality simulation and training, education and others. To designing stereoscopic perspective model correctly is one of the pivotal technology in generating stereoscopic computer imaging. In this paper,the basic principle of computer stereoscopic display and the geometric model for stereoscopic viewing are discussed,and several constraints having a direct bearing on the viewability of the stereogram are described.
