描述了一种使用两种热模型的多焦点图形可视化和导航技术：热传导模型和热辐射模型。该技术将力定向布局技术与热模型融为一体。它为焦点节点或焦点区域提供虚拟热能。热量影响链路和其他节点的温度，然后温度决定节点和链路的大小和长度等属性。用Java编程语言和Java 3D类库实现了一个原型浏览器。该浏览器可以在2D或3D视图中交互地可视化一般的图形结构。它允许我们同时拥有多个正焦点和负焦点，并使我们能够通过使用散热指针在图形中导航。
Describes a multiple-focus graph visualization and navigation technique using two heat models: a heat conduction model and a thermal radiation model. The proposed technique integrates force-directed layout techniques with the heat models. It provides virtual heat energy to focus nodes or a focus region. The heat influences the temperatures of link and other nodes, and then the temperatures determine the attributes, such as the sizes and lengths, of the nodes and links. A prototype browser using the proposed technique has been implemented with the Java programming language and the Java3D class library. The browser can visualize a general graph structure interactively in a 2D or 3D view. It allows us to have both multiple positive foci and negative foci, and enables us to navigate in a graph by using a heat-radiating pointer.
