Application of Virtual Reality-based Cloud Computing in Digital Creation of Dabie Mountain Culture

This paper looks at 3D model retrieval techniques for digital virtual workshops in cloud computing. The global D2 shape distribution features are first used to sort the models for initial retrieval. Then the local curvature features are used to further optimize the sorted results to obtain the final retrieval results. Through the historical and cultural theme scene design, stage performance scene design, and interactive performance design to enhance the immersive experience of the corresponding cultural creations, the creative inheritance and dissemination mode of Dabie Mountain culture in the new period is created. The results show that the difference in the percentage of attention points in the landscape node area is significant, P=0.032, indicating that the virtual reality experience group is better able to meet the needs of the experience. The weights of the three evaluation dimensions of the virtual experience of Dabie Mountain folk song culture are, in order, mood design (0.4073) > scene design (0.3814) > context design (0.2113). Designing multi-sensory (visual, auditory, olfactory, tactile) is of the highest importance. In terms of interactive experience, more attention is paid to the timeliness and accuracy of feedback, as well as the guidance of operations. In terms of emotional experience, more attention is paid to the sense of pleasure, surprise, and satisfaction. In the cultural experience, more attention is paid to traditional folk songs and historical architectural displays.
