摘要

本文描述了一种无向加权图的沉浸式动态可视化方法。使用Fruchterman-Reingold方法，在虚拟现实系统中绘制了力定向图。用户可以浏览数据，也可以使用控制器移动顶点，而网络显示则根据牛顿物理学实时重新排列。除了所用方法背后的物理原理外，本文还解释了其实现的最相关的计算机制，使用Unity、SteamVR和HTC Vive等虚拟现实系统（源程序包可供下载）。已经发现，该方法允许对具有10个2个顶点数量级的图进行直观的探索，并且顶点的动态挤出和网络结构的实时重新调整允许对顶点与网络其余部分的关系进行直观的理解。基于这一观察，提出了未来可能的发展。

Virtual-Reality graph visualization based on Fruchterman-Reingold using Unity and SteamVR

The paper describes a method for the immersive, dynamic visualization of undirected, weighted graphs. Using the Fruchterman-Reingold method, force-directed graphs are drawn in a Virtual-Reality system. The user can walk through the data, as well as move vertices using controllers, while the network display rearranges in realtime according to Newtonian physics. In addition to the physics behind the employed method, the paper explains the most pertinent computational mechanisms for its implementation, using Unity, SteamVR, and a Virtual-Reality system such as HTC Vive (the source package is made available for download). It was found that the method allows for intuitive exploration of graphs with on the order of 10 2 vertices, and that dynamic extrusion of vertices and realtime readjustment of the network structure allows for developing an intuitive understanding of the relationship of a vertex to the remainder of the network. Based on this observation, possible future developments are suggested.

期刊介绍： Information Visualization is essential reading for researchers and practitioners of information visualization and is of interest to computer scientists and data analysts working on related specialisms. This journal is an international, peer-reviewed journal publishing articles on fundamental research and applications of information visualization. The journal acts as a dedicated forum for the theories, methodologies, techniques and evaluations of information visualization and its applications. The journal is a core vehicle for developing a generic research agenda for the field by identifying and developing the unique and significant aspects of information visualization. Emphasis is placed on interdisciplinary material and on the close connection between theory and practice. This journal is a member of the Committee on Publication Ethics (COPE).
