Abstract This paper makes comprehensive use of virtual reality, virtual plants, and other technologies, integrates parametric plants and buildings and other modeling methods, and flexibly manages and organizes all kinds of garden elements through digital vector layers. Based on the OSG graphic rendering engine, it visualizes all sorts of 3D garden landscape models. Combining multi-sensory expressions, the parameter-driven multi-sensory design of virtual Chinese gardens is comprehensively constructed. The findings indicate that the scheme with decentralized placement on both sides has a receding time of 312s, and the area of human flow density has been enhanced. In the soundscape design, the birdsong sound was favored more, and the mean value of the birdsong sound scores in the botanical garden, plaza, and stream was 4.43. The Sig values of experiential, realism, interactivity, and content richness between Group A and Group B were all less than 0.05. Therefore, this paper successfully designs and realizes multisensory interactions between people and the garden scenario design.
