Application of Virtual Reality and CAD Technology in the Design and Development of Cultural Creativity Products

Abstract

At present, computer technology has been greatly developed, and computer-aided technology has appeared, which is applied to all kinds of modern product design. VR (Virtual reality) and CAD (Computer aided design) technologies have played a great role in the design, production and sales of modern cultural creativity (Culture and creativity) products. This article discusses the application of VR and CAD in the research and growth of cultural creativity products, and puts forward an innovative 3D modeling method of product modeling based on VR and CAD. The key links and technologies of virtual environment modeling are emphatically analyzed, including 3D modeling optimization process, structure optimization, model optimization and hierarchical simplification algorithm based on k_dop. Simulation results show that the accuracy of the proposed algorithm is high, and it is basically stable above 90%. The fastest running speed can reach 0.201s. Moreover, the model achieves the purpose of realism, real-time and interactivity, which can meet the actual needs. In the design of cultural creativity products, VR and CAD not only improve the design quality, reduce the production cost, but also shorten the design time of cultural creativity products. The method in this article provides new technical means for the research and growth of cultural creativity products, and opens up the possibility of product design and innovation.
