As a national intangible cultural heritage, the Olunchun "Mosukun" lacks the channel of integration with modern scientific and technological innovation, resulting in low communication efficiency, and is facing a severe problem of protection and inheritance. Therefore, this paper takes the Olunchun "Mosukun" as the research object, and with the application advantages of VR technology, 3D modeling technology and visual interaction technology, the unique characters, stories, rap forms and other intangible elements in "Mosukun" culture are transformed into design materials by software programs such as 3ds Max, Photoshop, Unity3D, etc., which are integrated into the visual communication design, and a three-dimensional visual platform is constructed by using C# language in combination with ASP.NET framework. It not only enhances the performance result of visual communication design, but also promotes the organic combination of traditional culture and modern artistic creation, enriches the cultural connotation of visual communication works, and is more beneficial to the rapid promotion of "Mosukun" culture, which has made a good demonstration for the realization of brand building and development.
