摘　　要：采用传统的几何绘制方式建立真实模型繁琐且需要专用绘制硬件，绘制质量和场景的复杂性受到很大限制，基于图象的虚拟场景绘制技术能克服传统方式的困难与缺陷，它是实现对虚拟场景建模和实时绘制的新的有效方法，本文介绍和分析了当前图象绘制技术的一些主要方法，提出改进途径。The traditional geometry- based rendering systems usually require laborious modeling and expensive special purpose rendering hardware. The rendering quality and scene complexity are often restricted due to the real- time constraint.Image-based rendering is a powerful new approach.It can conquer above difficulty and defect. Leading techniques for image-based rendering are introduced and analyzed in this paper and new ways to improve existing methods are proposed.
