Benchmark Dataset for the Voronoi Diagram of 3D Spherical Balls

1. Summary This is a dataset to be used for the construction of the Voronoi diagram of 3D spherical balls (VD-B3). The dataset consists of sphere arrangements including general, anomaly, and extreme cases. The dataset also includes protein models downloaded from RCSB Protein Data Bank (PDB). The dataset can be used as a standard benchmark dataset to verify and validate the accuracy, efficiency, and robustness of the construction algorithm. 2. Dataset description 2.1. Sets of random 3D spherical balls within a spherical container: BALLCLOUD, BALLSMALLSET[1,10], VISUALSET (Vis-I-10). Hereafter a ball denotes a 3D spherical one. 2.2. Sets of random balls touching a reference sphere: EXTREMESET, VISUALSET (Vis-V-20, Vis-VI-6, Vis-VII-20) 2.3. A set of balls on a grid: VISUALSET (Vis-IV-60) 2.4. Sets of balls for anomaly case in Voronoi diagram: ANOMALYSET, VISUALSET (Vis-II-5, Vis-III-5) 2.5. A set of protein models downloaded from RCSB Protein Data Bank: PROTEINSET 3. File format The integer of the first line denotes the number of balls. Each following line contains the definition of each ball with 5 fields in order: id (integer); x-, y-, z- coordinate of ball center (floating-point number); radius of ball (floating-point number). The floating-point number is represented up to six decimal places. Each file in BALLCLOUD, BALLSMALLSET, EXTREMESET, ANOMALYSET, VISUALSET follows the data format.1. 概述 本数据集用于构建三维球体沃罗诺伊图（Voronoi diagram, VD-B3），包含通用、异常与极端场景下的球体排布，同时收录了从RCSB蛋白质数据银行（RCSB Protein Data Bank, PDB）下载的蛋白质模型。本数据集可作为标准基准数据集，用于验证构建算法的准确性、效率与鲁棒性。 2. 数据集说明 2.1 球形容器内的随机三维球体集合：BALLCLOUD、BALLSMALLSET[1,10]、VISUALSET（Vis-I-10）。下文所述球体均指三维球体。 2.2 与参考球体相切的随机球体集合：EXTREMESET、VISUALSET（Vis-V-20、Vis-VI-6、Vis-VII-20） 2.3 网格分布球体集合：VISUALSET（Vis-IV-60） 2.4 沃罗诺伊图异常场景专用球体集合：ANOMALYSET、VISUALSET（Vis-II-5、Vis-III-5） 2.5 从RCSB蛋白质数据银行下载的蛋白质模型集合：PROTEINSET 3. 文件格式 首行的整数（integer）表示球体总数量。后续每行依次以5个字段定义单个球体，字段顺序为：球体ID（integer）、球心x、y、z坐标（浮点数（floating-point number））、球体半径（浮点数）。浮点数保留至多六位小数。BALLCLOUD、BALLSMALLSET、EXTREMESET、ANOMALYSET、VISUALSET下的所有文件均遵循此数据格式。
