Abstract

Technically, because of the limited dimensions of the presentation media, and psychologically, because of the limited human attention span, graphical program visualization in computer assisted reverse engineering becomes increasingly difficult with scale. This problem becomes compounded when multi-perspective visualization is taken into consideration. In this research we present a system called HVIEW, which attempts to overcome the problem of scale by logical decomposition. HVIEW can present a graphical visual of a computer program at various abstraction levels from diverse perspectives as interactively requested by the user. HVIEW logically formulates abstract function and data objects to construct compressed immediate program representations and organizes them into independent data and function hierarchies. Whereas, these hierarchies provide the mechanism of flexible abstraction, a user specifiable query filter creates an assortment of perspectives on the rendered visual of the modelled code.<>

将抽象灵活性与不同的程序透视图集成在一起
从技术上讲,由于呈现媒介的尺寸有限,从心理上讲,由于人类注意力的持续时间有限,计算机辅助逆向工程中的图形程序可视化变得越来越困难。当考虑多视角可视化时,这个问题变得更加复杂。在这项研究中,我们提出了一个名为HVIEW的系统,它试图通过逻辑分解来克服规模问题。HVIEW可以根据用户的交互要求,从不同的角度在不同的抽象层次上呈现计算机程序的图形化可视化。HVIEW将抽象的函数和数据对象进行逻辑表述,构造压缩的即时程序表示,并将它们组织成独立的数据和函数层次。然而,这些层次结构提供了灵活的抽象机制,用户可指定的查询过滤器在建模代码的呈现视觉上创建了各种透视图
