Source Viewer 3D (sv3D) is a software visualization framework that builds on the SeeSoft metaphor. It brings a number of enhancements and extensions over SeeSoft-type representations. In particular it creates 3D renderings of the raw data and various artifacts of the software system and their attributes can be mapped to the 3D metaphors at different abstraction levels. It implements improved, object-based user interactions, is independent of the analysis tool, and it accepts a simple and flexible input in XML format. The output of numerous analysis tools can be easily translated to sv3D input format and the design and implementation of our system is extensible.
