In the context of the rapid development of AI area, VR technology is raising the public and researchers’ attention. This study constructs a VR clothing catwalk based on the Unity 3D game engine in the AI background. This article focuses on the study of Unity 3D to construct the scenes and costumes of the clothing catwalk and then combine the immersive experience of VR to achieve the feeling of VR. Therefore, this article designs the scenes and model costumes of the VR clothing show by analyzing the VR technology in the context of the AI environment, combined with the Unity 3D game engine. It optimizes the VR clothing show based on Unity 3D game engine designed in this paper through design performance test experiment and visual positioning comparison experiment and then investigates and analyzes the optimized VR clothing show. Based on user feedback, this article completes the function of VR clothing show and compares it with the traditional online clothing show. The experimental results show that the sensory evaluation given by users is 22.02% higher than that of users of traditional online clothing shows. In the clothing catwalk based on Unity immersive VR, the user's rating for the fluency of watching is 10.99% higher than that of the traditional online clothing catwalk.
The study expects to explore the sustainable logistics management of foreign trade enterprises, help to further adapt to the development mode of economic globalization at this stage, reduce the international trade cost of enterprises and promote the overall trade development of enterprises. Logistics service providers of foreign trade enterprises are set as the research object to analyzes the problems existing in internal logistics management from the perspective of enterprise logistics. According to the relevant principles of analytic hierarchy process (AHP), the corresponding solutions are proposed. Through the actual investigation and analysis, first, the main problems of modern logistics enterprises are underdeveloped logistics management technology, low degree of information, low work efficiency and high logistics risk. Second, the enterprise logistics management index is divided into five indicators, namely, enterprise service level, enterprise operation qualification, logistics management ability, risk control ability and transportation location advantage. Among the five indicators, service level accounts for the largest proportion, for 30.23%. Four different service providers are scored, and the highest score is 7.5717, which proves the practicability of AHP. Finally, the optimization management strategy is proposed for similar logistics enterprises. The accomplishment of the study can help enterprises reduce costs, continuously improve the level of logistics management, and provide a theoretical basis for the sustainable development of enterprises, which has certain practical significance and can provide scientific and effective reference for subsequent research.
