Research on National Costume Design Based on Virtual Reality Technology

Cheongsam has the unique costume culture characteristics of the Chinese nation and is a classic style of traditional Chinese costumes. At the same time, with the rapid development of science and technology, 3D virtual technology plays an increasingly important role in the garment intelligent manufacturing industry. Therefore, how to combine 3D virtual technology with the development of women's cheongsam clothing products is of great significance, which can overcome the limitations of time and space and effectively improve the efficiency of clothing pattern design. To solve this problem, a design method for national costume based on virtual reality technology is proposed. First of all, the modeling and structural characteristics of cheongsam are analyzed. Secondly, different curve fitting methods are applied to human body feature recognition, and cubic polynomial fitting is selected to complete the feature recognition of the human body model in a virtual environment. Then, in order to prevent the penetration between clothing and the human body, the collision detection function based on the AABB bounding box is added, and a method based on linear sensitivity is used to map 2D to 3D. Finally, the model of a cheongsam costume is created by using the clothing simulation Marvelous Designer software, and the effectiveness of the proposed virtual cheongsam costume simulation design method is verified by subjective evaluation indexes.
