Application of Virtual Reality Technology in the Digital Inheritance of Intangible Cultural Heritage

Virtual reality visualisation design can be used as a new starting point for inheriting and preserving nontraditional heritage with authenticity and creativity. Virtual reality technology can reasonably coordinate the human-machine relationship and point out the direction of new artistic expression. The aim of this paper is to study the digital inheritance of intangible heritage based on virtual reality technology. In this paper this paper describes the whole process of digitisation of intangible cultural heritage, designs a system for digitisation of intangible cultural heritage and assesses public satisfaction. In order to improve the rendering efficiency, the LOD algorithm in Three.js was modified to make the model calls in the algorithm more reasonable by using physical conditions and user interests. Experimental results show that the algorithm can improve the rendering efficiency of the browser and improve user interaction and experience. The average human service perception was 4.6, with a standard deviation of 0.72. Therefore, virtual design improvement of intangible cultural heritage digital inheritance through virtual reality technology can effectively enhance the humanized service effect.
