摘要： Feudal historical buildings with ritual elements are the basic scenes of many excellent games, However,researches on design methods for factual historical buildings in game are still out of demands both on precision and migration capability.Aiming at this problem,this paper deeply reflects on the semantic or ontology modeling of ritual elements and their integration model with the game engine and PCG.firstly,we comprehensively provides a ritual semantic model that can be used for automatic generation of ancient buildings in game historical scenes. Secondly,we designed the ritual semantic model to provide the loose coupling capability with the game environment and building system based on the ontology design pattern.Thirdly,through the analysis of the ritual semantic system of Style Lei, the experimental verification of the ritual semantic model is carried out, and the migration capability of the ritual semantic model is proved by comparison.The models and experiments proposed in this paper and even the analysis of the ritual elements in the Chinese style Lei building system can provide useful references for both game scene auto design and related researches.
