In this research, a design system with a virtual reality function was developed. The virtual world was realized by using GL4Java, liquid crystal shutter glasses, sensor systems, etc. And the Multi-Agent CAD system with product models, which had been developed before, was integrated with the VR design system. A prototype system was developed for highway steel plate girder bridges, and was applied to a design problem. The application verified the effectiveness of the developed system. 2004 urn:nbn:de:gbv:wim2-20111215-2146 10.25643/bauhaus-universitaet.214 Professur Informatik im Bauwesen OPUS4-244 Wissenschaftlicher Artikel Semenov, Vitaly; Alekseeva, Elena; Tarlapan, Oleg Virtual Construction using Map-based Approach The paper presents a general map-based approach to prototyping of products in virtual reality environments. Virtual prototyping of products is considered as a consistent simulation and visualization process mapping the source product model into its target visual representations. The approach enables to interrelate formally the product and visual information models with each other by defining mapping rules, to specify a prototyping scenario as a composition of map instances, and then to explore particular product models in virtual reality environments by interpreting the composed scenario. Having been realized, the proposed approach provides for the strongly formalized method and the common software framework to build virtual prototyping applications. As a result, the applications gain in expressiveness, reusability and reliability, as well as take on additional runtime flexibility... 2004 urn:nbn:de:gbv:wim2-20111215-2447 10.25643/bauhaus-universitaet.244 Professur Informatik im Bauwesen OPUS4-231 Wissenschaftlicher Artikel Kang, Shihchung; Miranda, Eduardo Automated Simulation of the Erection Activities in Virtual Construction The goal of the research is the development of a computer system to plan, simulate and visualize erection processes in construction. In the research construction cranes are treated as robots with predefined degrees of freedom and crane-specific motion planning techniques are developed to generate time-optimized and collision-free paths for each piece to be erected in the project. Using inverse kinematics and structural dynamics simulation, the computer system then computes the crane motions and velocities necessary to achieve the previously calculated paths. The main benefits of the research are the accurate planning and scheduling of crane operations leading to optimization of crane usage and project schedules, as well as improving overall crane safety in the project. This research is aimed at the development of systems that will allow computer-assisted erection of civil infrastructure and ultimately to achieve fully-automated erection processes using robotic cranes... 2004 urn:nbn:de:gbv:wim2-20111215-2310 10.25643/bauhaus-universitaet.231 Professur Informatik im Bauwesen
