Multi-agent interaction in a complex virtual design environment

New technological achievements and research results allow for the creation of innovative design tools for architects, that do not originate from paper-based paradigms but instead make optimised use of the present technology and programming concepts. The core of our system is comprised of an intuitive interactive modeling tool named SCULPTOR. It runs in a virtual reality set-up, where the user can use 3D-glasses to experience rooms and 3D-input devices to model in three dimensions. The interface is free from widget-like buttons or menus, so that the user is undisturbed when moving into the virtual world of the design. The 3D-model can be generated in a sketch-like fashion using solids and voids. The objects in this system can contain forms of intelligence to produce such behaviour as: falling because of gravity, collision avoidance, and autonomous motion. Interactive behaviour can also be assigned to the objects. Autonomous agents are combined with the modeling tool to enhance the designer support. These are agents that enhance the virtual environment, agents that take over tasks, and agents that help to test the design. The system shows new interface and interaction approaches that support the architectural design process intelligently.
