项目摘要
In this study, we proposed "Multi-sphere Scheme" to efficiently pack given two- or three-dimensional objects in a compact space, designed all the components of the scheme, and investigated fundamental theory on geometrical packings and graph drawings. We designed an algorithm that can directly transform given triangle-mesh data into data for Multi-sphere Scheme based on a graph-theoretical analysis. We developed a 3D visual interface for Multi-sphere Scheme, by which we can easily check computational results in a visualized form. We greatly improved our solver for packing rectangles so that a long-standing open benchmark instance is solved for the first time by our new solver. As for the theory part, we found a 2D representation of triconnected graphs so that a useful triconnected decomposition can be easily obtained, and a characterization of the graphs of non-convex polytopes in a certain class.In particular, the latter result is the first such result since Steinitz' theorem, a characterization of the graphs of convex polytopes is found 80 years ago.
在本研究中,我们提出了在紧凑空间中对给定的二维或三维物体进行高效包装的多球体方案,设计了该方案的所有组成部分,并研究了几何包装和图形绘制的基本理论。在图论分析的基础上,设计了一种将给定的三角网格数据直接转换为多球体数据的算法。我们为多球体格式开发了一个三维可视化界面,可以方便地以可视化的形式查看计算结果。我们极大地改进了用于填充矩形的求解器,因此我们的新求解器首次解决了一个长期存在的开放基准实例。在理论部分,我们得到了三连通图的二维表示,从而可以很容易地得到一个有用的三连通分解,并刻画了某类非凸多面体的图,特别是后者是自80年前Steinitz定理发现凸多面体的图的刻画以来的第一个结果。
