碩士 === 國立臺灣師範大學 === 資訊教育學系 === 95 === Debugger is a tool that programmers use to find the bugs in the program. It typically provides textual debugging information to programmer and is usually combined into the IDE (Integrated Development Environment). Because the textual debugging information only displays numerical values of variables, it is considered inadequate for understanding complicated data structures. There are some debugging tools that can display debugging information in 2-dimension, which is more understandable than textual information. However, rendering data in a 2-D display is often limited by the view port. When too much information is rendered together, it is useless. In this thesis, not only do we extend the rendering to 3-D but also design an object-oriented framework which enables the separation of VM programming from visualization system and particularly the compositionality of visualization metaphors.. An experimental layout visualization metaphor under the framework is implemented to rendering tree data structure, a commonly used data structure during programming.
