边界光场

提出一种新的基于图像的绘制方法——边界光场．该方法基于3D全光函数的思想，并使之与场景几何相结合．该方法克服了已有的IBR漫游系统的一些缺陷，利用自适应的的全光采样模式，根据场景复杂度或用户要求组织采样数据，降低了场景数据量；由于场景几何的参与，纠正了较大的深度变形；新的采样数据组织模式去除了对漫游范围的限制．文中方法可有效地应用于虚拟或真实场景漫游系统中．

Boundary Light Fields

A new approach to IBR technique is presented based on 3D plenoptic function and utilizing the approximate scene geometry model Through introducing planar geometric boundary of scene, our approach shows some merits in comparison with previous similar rendering techniques It can sample the ray set in an adaptive way according to the scene complexity or special user demands, thus reducing the plenoptic sampling data effectively without degeneration of rendering quality; it restricts the vertical distortion to an acceptable limit with correct scene depth; and by arranging the ray set focusing on scene objects, an arbitrary sampling track can be used, which can allow observer move freely at will Boundary light fields is a simple IBR technique, can be easily employed in walkthrough system of synthetic or real scene
