Abstract

We propose the technology of full life-cycle automatic animation generation of Chinese traditional architecture and summarize a software system that implements this technology. Starting from a pseudo-natural language description of the architecture, until the generation of a 3D animation demonstrating the construction of this building, the whole process is performed automatically step by step, including reasoning of the construction sequence, computation of the size and position of each piece of wood, generation of a qualitative animation specification, and generation of a quantitative animation specification. As a result, the software system realizes more than 180 architectures in three main types of Chinese traditional timber structures, thirteen types of Dougong, and six types of Chinese pagodas. In addition to standard architectures, our technology can also be applied to generate animations for real-world buildings. Potential applications of such technology include demonstration systems in museums where the visitor describes what kind of building he wants to see and the system can accordingly construct the building in real time. We use artificial intelligence techniques including knowledge representation and reasoning for the Semantic Web to support the automation. More precisely, one ontology and four rule bases were built, where we used OWL DL, SWRL and Jess to capture the domain knowledge. Our experience in exploiting the current Semantic Web technologies in real-world application systems indicates their prominent advantages (such as the reasoning facilities and modeling tools) as well as the limitations (such as low efficiency).
