The project ViSE3D aims at visualising in three dimensions code structures of Java software systems. We have developed several visualisation tools for code comprehension and analysis as well as for both re- and reverse-engineering purposes. 3D space allows to display a large amount of data with optimal visual ingress, and using specific layout algorithms optimises space utilisation with respect to interpretability of the code structures displayed. In this challenge report, we explore the Eclipse source code with our tool VisMOOS.
