摘要
提出了一种多面体的DEXEL化算法及一种三向DEXEL模型。与单向DEXEL模型相比,三向DEXEL模型能更精确地表示一个型体。在同一三向DEXEL模型空间,实现并、交、差布尔运算。将三向DEXEL模型用于飞机复合材料零件设计,设计了蜂窝结构、方管、圆管结构。在Java2.0与Java 3D环境下编程,实现并验证了所有算法。
It gives a dexelization algorithm of polyhedrons.h suggests a three directions DEXEL model of polyhedrons.Compared with a single direction DEXEL model,the three directions DEXEL model could express a model more precisely.Under the same three directions DEXEL space,Boolean operations such as union,intersection,and subtraction are implemented.Use the three directions DEXEL model in aircraft composite parts design.Under Javal 2.0 and Java 3D,these algorithms are tested.
