摘　　要：基于图像的绘制技术(Image-based Rendering,IBR)近年来引起广泛的关注,目前的基于图像的绘制技术(IBR)可以根据他们依赖场景几何信息的程度分为三类:无几何信息的IBR绘制、部分几何信息的IBR绘制和全部几何信息的IBR绘制。通过对三类技术特征及其数学描述的讨论,从中得出结论:在IBR技术中图像和几何信息的双重应用表明IBR和传统的基于三维几何的图形学可以统一成一个有机整体。Image-based rendering techniques have recently received much attention, Previous image-based rendering techniques can be classified into three categories according to how much geometric information is used: rendering without geometry, rendering with implicit geometry, and rendering with explicit geometry (either with approximate or accurate geometry). Discussed the characteristics of these cate- gories and their representative methods, The continuum between images and geometry used in image-based rendering techniques suggest that image-based rendering with traditional 3D graphics can be united in a joint image and geometry space.
