Multi-sensory Design And Expression Research Of Chinese Classical Garden Based On Virtual Reality

With the rapid development of virtual reality technology,man-machine interaction technology,internet technology and so on,the landscape architect's working methods have gradually evolved from hand-drawn,two-dimensional software representations to three-dimensional software representations or landscape video roaming and other methods.However,these methods have disadvantages such as poor simulation effect,lack of interaction and incomplete display.Nowadays,people's requirements for landscapes performance are gradually increasing.They can't be satisfied with these basic methods,they also want to participate in them,in other words,communicate and interact with the landscape,get an immersive sense of immersion,and even more,hope to obtain a variety of sensory experiences,such as sight,hearing,smell and so on.Based on a survey of documents,case studies,and so on,this paper describes the current situation of research on virtual reality both at home and abroad,and focuses the discussion on the application of landscape roaming,including the application foundation,the necessity and possibilities for application.The system has designed and produced the interactive system of the classical garden of Yangzhougeyuan Garden in China.The system first collects the basic data of Yangzhougeyuan gardens and carried out fieldwork,secondly,made the virtual scene by software,production phase is divided into three steps: first in first,create a CAD plan of the garden based on the sketches,then create buildings models and sketches in 3Dsmax,and finally add plants,ponds,sky boxes and roaming controllers in Unity3 D.This paper uses the virtual reality method to realize the landscape roaming design.At the same time,in order to solve the immersion and interaction better,it explored the experience theory of experience,such as vision,hearing,olfaction,taste and tactile sense.On the basis of the existing virtual reality experience mode,the multi-sensory expression is applied to the virtual reality roaming smell experience through upgrading and transformation.After the completion of the production of Yangzhougeyuan system,detailed system testing was conducted to find the problems an resolve them.In the end,through debugging,the final implementation was released to the network.The system has good rendering effect,strong interaction,convenient operation,full functions and short development cycle,finally realized the virtual experience of Chinese classical gardens perfectly.The system runs well.At the same time,it can satisfy the users experience,it also has practical significant for the development of the tourism of Yangzhougeyuan garden and the promotion of the development of the garden design industry.In addition,the application of multi-sensory virtual roaming is also very intensive.For example,many industries have extensive development such as real estate development,digital city construction,teaching,tourism and other industries.Finally,this paper puts forward the sense of smell experience of virtual reality scene,and also has some ideas for the development of other multi-senses(such as touch,taste,etc.).
