复杂数据的三维表示和检查是许多数据分析领域中经常使用的策略。现有的数据挖掘软件通常缺乏使用户能够交互地探索3D数据的功能,特别是如果希望使动态图形表示在网络上直接可见的话。在本文中,我们介绍了Vrmlgen,这是一个用于统计编程语言R的软件包,用于创建虚拟现实标记语言(VRML)和LiveGraphics3D等Web格式的3D数据可视化。Vrmlgen可用于生成3D图表和条形图、具有密度估计等值线表面的散点图,以及高度图、3D对象模型和参数函数的可视化。为了获得更大的灵活性,用户还可以通过统一的界面访问低级绘图方法,并可以自由地将不同的函数调用组合在一起,以创建新的高级绘图方法。此外,我们还提供了一个网络工具,允许用户在线可视化3D数据并测试vrmlgen的一些功能,而不需要在他们的计算机上安装任何软件。
The 3-dimensional representation and inspection of complex data is a frequently used strategy in many data analysis domains. Existing data mining software often lacks functionality that would enable users to explore 3D data interactively, especially if one wishes to make dynamic graphical representations directly viewable on the web. In this paper we present vrmlgen, a software package for the statistical programming language R to create 3D data visualizations in web formats like the Virtual Reality Markup Language (VRML) and LiveGraphics3D. vrmlgen can be used to generate 3D charts and bar plots, scatter plots with density estimation contour surfaces, and visualizations of height maps, 3D object models and parametric functions. For greater flexibility, the user can also access low-level plotting methods through a unified interface and freely group different function calls together to create new higher-level plotting methods. Additionally, we present a web tool allowing users to visualize 3D data online and test some of vrmlgen's features without the need to install any software on their computer.
