3D Modeling for Non-Expert Users with the Castle Construction Kit v0.5

We present first results of a system for the ergonomic and economic production of three-dimensional interactive illustrations by non-expert users like average CH professionals. For this purpose we enter the realm of domaindependent interactive modeling tools, in this case exemplified with the domain of medieval castles. Special emphasis is laid on creating generic modeling tools that increase the usability with a unified 3D user interface, as well as the efficiency of tool generation. On the technical level our system innovates by combining two powerful but previously separate approaches, the Generative Modeling Language (GML) and the OpenSG scene graph engine.
