The Virtual Roaming Design Of Changsha Tongguan Kiln Heritage Park Based On WebGL

Changsha Kiln is located near Shizhu Lake,Dingzi Town,Wangcheng District,Changsha City.It began in the early Tang Dynasty,flourished in the middle and late Tang Dynasty,and declined in the Five Dynasties.It is an important representative of Huxiang culture.As a place to display the cultural space of Changsha Kiln,Changsha Tongguan kiln Heritage Park is an important intangible cultural heritage.This paper studies the digital preservation of cultural heritage in Changsha Tongguan Kiln Heritage Park based on WebGL.This topic is the design of virtual roaming system with artistic design based on actual scenes.In the process of system implementation,WebGL virtual scene development technology based on three-dimensional modeling is used.The key technologies are virtual reality technology,three-dimensional modeling technology and WebGL technology.In the implementation process of system,WebGL virtual roaming system use three key technologies which are virtual reality technology,three-dimensional modeling technology and WebGL technology.Compared with other virtual reality systems,WebGL virtual roaming system only need simpler equipment.WebGL virtual roaming system based on three-dimensional modeling is an excellent interactive three-dimensional promotion platform which has immersions and can be displayed through web pages.Compared with other virtual reality systems which requiring complex devices,The virtual roaming system based on is more cost effective.Through the virtual roaming system of Changsha Tongguan Kiln Heritage Park based on WebGL,we can get more intuitive and convenient propaganda methods than traditional media,and it also has a good propaganda effect on local ceramic craftsmen and cultural industries of Changsha Kiln.Firstly,This paper investigates and analyses the research background of the project which expounds the key technologies and related technical difficulties,and analyses the digitization case of WebGL-based cultural heritage.Then,Completed the design of virtual roaming system with artistic design based on actual scenes through the data from field visits.After that,described the three-dimensional construction process and Unity3 D development process of the virtual roaming system of the Heritage Park in detail.Finally,studied how to publish the WebGL and the issues in the release process.Four key technical problems have been solved in the process of system implementation which are optimization of scene,optimization of interior and exterior lighting effect,dizziness of scene and scene of reality.For optimization of scene,this project mainly describes the 3DMax modeling stage to optimize the structure and area of the model,and the Unity development stage to optimize the number of terrain vegetation,lighting effect and so on.For the optimization of interior and exterior lighting effect,through the baking technology and a small amount of Spotlight to reduce the quality of real-time operations.For dizziness of scene,this project through Shorten experience distance and controlling the first person’s walking speed and footfall to relieve the dizziness.For scene of reality,through the plug-in unit Post Processing Stack of Unity to enhance the reality of the scene.
