Integration of four-dimensional computer-aided design modeling and three-dimensional animation of operations simulation for visualizing construction of the main stadium for the Beijing 2008 Olympic games

摘要

In this paper, we give a state review of modeling methodologies for four-dimensional computer-aided design (4D CAD) and three-dimensional (3D) animation of operations simulation. We then present our efforts of integrating 4D CAD and 3D animation of operations simulation to facilitate the construction planning of the main stadium for the Beijing 2008 Olympic Games (nicknamed the "Bird's Nest"). We propose a "zoom" interface between 4D CAD and 3D animation of operations simulation to enable a natural synergy of two separate, but organically linked research streams. For concept proving and application demonstration, we seamlessly integrated two computer systems resulting from previous in-house research to plan and visualize the construction of the "Bird's Nest" in close collaboration with the main contractor. The integrated construction planning methodology is found instrumental in visually and intuitively conveying the master project schedule and detailed operations plan for construction of the "Bird's Nest".
