In order to better inherit and carry forward the traditional architectural culture, and present the charm of Chinese traditional architectural culture to everyone more vividly and concretely, we designed and developed the work "Pavilion in Painting-VR Chinese Traditional Architectural Culture" based on Steam VR and Unity. Hope to provide users with an immersive, different from the reality of traditional Chinese architectural culture tour. The works are divided into three parts: the main scene, the mortise and tenon display scene and the architectural display scene. The user can understand the basic knowledge related to architectural art in the main scene, and choose to jump to the relevant scene. The mortise and tenon joint display scene shows several commonly used mortise and tenon joint structures and introduces their corresponding knowledge and application scenarios, supplemented by animation to make it easier for users to understand the connection principle of mortise and tenon joint. The architectural display scene shows the charm of traditional architectural culture in the form of classic architectural cases. Users can roam freely in the scene, in the form of multi-angle view of the beauty of traditional architecture. The Pavilion in the Painting shows the style and knowledge of ancient Chinese architecture in the form of traditional Chinese ink painting. In the production process of the work, we use blender to model, use unity to make scenes and systems, and the work demonstration uses the way of recording real-time VR experience process video. The work innovatively combines the visual effects of ink painting with the content of traditional architecture, enriches the visual sensory experience and brings a more visually attractive content experience to the audience.
