algorithmS FOR TETRAHEDRAL NETWORK(TEN) generation

Geo-Spatial Information Science 2000年第1期3卷 11-16页

作者： LI Qingquan LI Deren WTUSM

The Tetrahedral Network(TEN) is a powerful 3-D vector structure in GIS, which has a lot of advantages such as simple structure, fast topological relation processing and rapid visualization. The difficulty of TEN application is automatic creating data structure. Although a raster algorithm has been introduced by some authors, the problems in accuracy, memory requirement, speed and integrity are still existent. In this paper, the raster algorithm is completed and a vector algorithm is presented after a 3-D data model and structure of TEN have been introducted. Finally, experiment, conclusion and future work are discussed.

In this paper the simple generation algorithms are improved. According to the geometric meaning of the structural reliability index, a method is proposed to deal with the variables in the standard normal space. With consideration of variable distribution, the correlation coefficient of the variables and its fuzzy reliability index, the feasibility and the reliability of the algorithms are proved with an example of structural reliability analysis and optimization.

＜正＞Briefly introduces the significance of research on controlled five-rod mechanism and lists the common low-pair of it,studied mainly on the controlled five-rod RRRPR mechanism which has a revolute-pair to make stable movement and a prismatic-pair to do corresponding compensate movement to meet the *** VC and OpenGL,based on advanced generation algorithm, to developed a controlled five-rod RRRPR mechanism visual system,this system can make mechanism simulation and analyze on condition given movement parameters,and also can do converse optimize design to recur several fixed points track;this system gives stronger support for theory researches and applications of the controlled five-rod RRRPR mechanism.

关键词： controlled five-rod RRRPR mechanism reverse design generation algorithm computer simulation
