DEVSView: A Tool For Visualizing CD++ Simulation Models

摘要

We present an application developed to visualize the results of a simulation created using the CD++ modeling and simulation toolkit. The tool, called DEVSView, allows users to create visualizations from the simulation log files generated by the CD++ toolkit. DEVSView has implicit support for DEVS and Cell-DEVS models, using OpenGL and the OpenGL Utility Toolkit for hardware accelerated rendering. DEVSView provides a graphical user interface and a text file format for the creation of visualizations. Visualizations, in DEVSView, consist of visual models that translate CD++ log files into animations. Each visual model corresponds directly to an atomic or coupled model from a CD++ simulation. These visual models contain visual states and event animations which are used to represent the simulation graphically. The user can set up the rules, to trigger state changes and event animations, within the GUI or in the visualization file, and the user can use the GUI to playback the visualization. Future work will include loading Maya model files for complex objects, and more advanced model positioning capabilities.
