SongScape: A Song Dynasty-Style Architectural Scene Design System Based on CGA Rules and Virtual Reality

The digital preservation and representation of ancient architecture hold significant importance, and the rapid and effective creation of stylized ancient buildings is a worthy research topic within this field. This paper, based on the ancient Chinese text “Yingzao Fashi,” analyzes the external features of Song dynasty architecture, including both palace-style and mansion-style buildings. Utilizing the CGA (Computer Generated Architecture) grammar rules, we propose CGA rules capable of generating Song-style architecture and explore the design concepts and implementation strategies. Building on this foundation, we have developed a design system within a virtual reality environment that supports the adjustment of parameters for individual buildings and collaborative design among multiple users. This system facilitates the rapid creation of Song-style architecture and offers new practical examples for immersive collaborative design.
