“…Worst-case optimal algorithms are presented by Devai and McKenna. 9 ' 13 The running time of more recent algorithms depends on the input size and the scene complexity. 3 ' 7,8 ' 12 ' 17 ' 18 ' 19 The fastest known algorithm for hidden-surface removal takes time 0(n 2 / 3+e fc 2 / 3 + n 1+c ), where n is the size of the input and k is the scene complexity.…”

“…The worst-case size of the visible image of a scene with O(n) edges is equal to O(n2) (Devai 1986, Schmitt 1981. This bound holds also for the size v of the visible image of a PTM, as shown by Cole and Sharir (Cole and Sharir 1989).…”

“…The problem of computing the visible image of a scene is generally referred as the Hidden Surface Removal (HSR) problem. The general quadratic upper bound to the space complexity of the visible image (Devai 1986, Schmitt 1981) applies also to a polyhedral terrain, thus giving a worst-case space requirement of O(n2) for a PTM with n vertices.…”

“…These requirements have encouraged the development of numerous properly structured visible line determination algorithms [1] such as Robert's Algorithm, Apple's Algorithm, Haloed Lines, The z-Buffer Algorithm, List-priority Algorithms, The DepthSort Algorithm, The Binary Space Partition(BSP) Tree Algorithm, Scan-line Algorithms etc. Recently Devai [3] proposed algorithm that runs in the O(n 2 ) time which is worstcase optimal but limited within fixed viewpoint.…”
