The study explores the application of three-dimensional clothing cutting in clothing contour design by reviewing literature on its development,theoretical basis,and technical points.The aim is to accurately capture and express designers'ideas about clothing form,texture,and dynamics through direct shaping in three-dimensional space.Stereoscopic cutting technology can visually present the three-dimensional effect of clothing after being worn,meeting the needs of modern consumers for personalized,differentiated,and comfortable clothing.This work provides inspiration and technical support for fashion designers,promoting continuous innovation and development of fashion design and production technology.
