A CityGML ADE for modeling Buddhist statues in 3D with semantic information

Aiming to support intraoperative and quantitative analysis on 3D Buddhist models, this paper presents a new mechanism of integrating semantic and attribute information within 3D geometries of Buddhist statues using the CityGML Application Domain Extension (ADE). For this purpose, a framework is designed for the process of ADE development which includes the definition of component Thesaurus, the establishment of semantic structure, the development of logic and physical models. By deploying this framework, the ADE is developed to model Buddhist statues in any type with semantic and attribute information, because with this ADE it is possible to decompose a statue into small meaningful component and record semantic and attribute information with the geometries. The ADE is tested by interactively selecting and visualizing one component of a Buddhist statue and validate that capability of modelling. 3D Buddhist statues modeled using this ADE can then support automatic analysis and calculations. Hence, this research work is one of the fundaments for the digitalization in the domain of culture heritage.
