摘要
介绍了概念格图形研究的现状,分析了目前常用的分层图.提出通过遍历概念格的各节点查看节点间的偏序关系来决定节点分布的概念格三维布局算法,并以此建立适当的Mesh对象来构造基于DirectX的三维概念格图形.同时还描述了一种概念格三维重构机制,较好地解决了复杂概念格的三维可视化问题.
This paper introduced the actuality of concept lattice graph, and analysed the layers layout graph. According to scanning all the nodes of the lattice and examining their order relations, a new algorithm of nodes layout in 3D space is proposed, and then constructs 3D lattice graph based on DirectX with establishing proper Mesh objects. Simultaneity a solution of 3D concept lattice reconstruction is described, and solves the problem of the visualization of some complicated concept lattice better.
