Evolution analysis with animated and 3D-visualizations

Abstract

Large software systems typically exist in many revisions. In order to analyze such systems, their evolution needs to be analyzed, too. The main challenge in this context is to cope with the large volume of data and to visualize the system and its evolution as a whole. This paper presents an approach for visualizing the evolution of large-scale systems which uses three different, tightly integrated visualizations that are 3-dimensional and/or animated and which support different analysis tasks. According to a first empirical study, all tasks are supported well by at least one visualization.

A Survey of Model Comparison Approaches and Applications

“…For example, model-based representation can be visualized through colouring (Ohst et al, 2003). Newer visualization approaches try to separate visualization from representation ( Wenzel, 2008;Wenzel et al, 2009). There is also an approach (Schipper et al, 2009) to extend visualization techniques for comparing text files to work with models by including additional features unique to higher level representations, such as folding, automatic layout, and navigation.…”
