We investigate the problem of finding the visible pieces of a scene of objects from a specified viewpoint. In particular, we are interested in the design of an efficient hidden surface removal algorithm for a scene comprised of iso-oriented rectangles. We propose an algorithm where given a set of [Formula: see text] iso-oriented rectangles we report all visible surfaces in [Formula: see text] time and linear space, where [Formula: see text] is the number of surfaces reported. The previous best result by Bern [Journal of Computer and System Sciences 40 (1990) 49–69], has the same time complexity but uses [Formula: see text] space.

一种空间最优的等向矩形隐面去除算法

我们研究从指定视点寻找物体场景的可见部分的问题。特别是,我们对为由等向矩形组成的场景设计一种有效的隐藏表面去除算法感兴趣。我们提出了一种算法,其中给定一组[公式:见文本]等向矩形,我们报告[公式:见文本]时间和线性空间中的所有可见表面,其中[公式:见文本]是报告的表面数量。Bern [Journal of Computer and System Sciences 40 (1990) 49-69] 之前的最佳结果具有相同的时间复杂度,但使用 [公式:见文本] 空间。
