摘要:
提出了三维空间中面对象相邻关系的判断算法CRAR与算法CRAR-DF.计算空间面对象与其他空间对象之间的距离,如果该距离小于给定的阈值,则认为面对象与该对象相邻.算法CRAR-DF在算法CRAR的基础上利用距离函数进行相邻关系的快速判断.实验结果表明,算法CRAR和算法CRAR-DF能够准确地判断面对象的相邻关系,且CRAR-DF具有较高的效率.
Abstract:
Algorithms CRAR and CRAR-DF are proposed for computing region adjacent relations in 3D space in this paper. Region objects and other spatial objects are adjacent if their distance is less than threshold value. Based on CRAR, CRAR-DF judges adjacent relations rapidly according to distance function. The experimental results show that algorithms CRAR and CRAR-DF are effective and CRAR-DF is more efficient.
