Under microcomputer circumstance a human-interactive graphic system is developed. An algorithm for hidden line removal based on improved appel algorithm and an algorithm for fast shaded graph are presented.

在表達比較復雜的零件內部結構時，設計和實現(xiàn)了一個任意三維形體階梯剖切算法，可以對任意零件實體進行任意方向亚洲三级片国产AV、任意位置連續(xù)的多刀剖切97sese社区，并且剖切操作方便国产操av。

A hidden line removing algorithm based on Divide-and-Conquer strategy working in object space is presented,whose speed is improved with the topological relation of the CSG+Brep,and stability is achieved with the ray method It runs well in the CAID syste

在物體空間中欧美老妓女视频，采用Divide－and－Conquer策略的隱藏線消除算法，利用CSG＋Brep的拓撲相關性和增加相關體素遮擋判斷提高隱藏線消除的速度超碰在线欧美精品，用射線法解決隱藏線消除的可靠性激情黄区1区。

This paper improved the traditional hidden line removal algorithm in a 3D solid scene: the Roberts algorithm, by integrating a new data structure into the traditional Roberts algorithm. In the end, implemented the hidden line removal algorithm which could meet the special requirement of outputting the hidden lines in the form of dotted line as the traditional solid geometry teaching does.

對三維立體場景中有名的線消隱算法——Roberts算法進行了研究并作了改進，在提高效率的同時將它與一定的數(shù)據(jù)結構相結合偷拍视频无码，實現(xiàn)了一種滿足立體幾何教學軟件中把隱藏線以虛線形式輸出的特殊要求的線消隱算法国产WWWWW免费在线观看。
