三维消隐算法研究

就目前计算机图形学研究的重要内容之一－消隐算法展开分析讨论。主要给出了消隐算法的定义及相关概念。阐述了目前已存在的几种消隐算法及其特点。并就其中的三种运用较广的消隐算法：平面公式法、罗伯兹算法、浮动水平消隐算法等给出具体的算法原理和算法实现。同时，进一步讨论了复合物体的消隐算法实现，给出不同消隐算法的分析比较。

Hidden Surface Removal for 3 - D Object

This paper extends the analysis and discussion of hidden surface removal algorithms, which is one of the important contents of computer graphics, difficult but pivotal The key of hidden surface removal algorithm is to judge if the surface of 3D modeling is visible Modeling is the foundation for 3D computer graphics, while hidden surface removal is the key of 3D modeling This paper defines the hidden surface removal algorithm and relevant concepts, discusses the existed algorithms and their properties, and details the principles and realization of three widely used algorithms, including surface formula algorithms,Robertz algorithm,float horizontal algorithm,with source codes attached at the end for reference Furthermore, this paper discusses the compound object algorithm, presents the analytical report of different hidden surface removal algorithms
