3D服装与2D样版相关参数的映射关系讨论——基于E-MTM技术

通过对简单锥体展平的分析,得到了凸点的三维曲面展平的平面之间映射关系方程,建立基础曲面3D到平面2D的角度参数映射关系。数字化服装三维形态中凸点的选择主要基于服装技术和造型曲面形态,上装主要集中在胸围截面的BP点和背部的背宽线的肩胛骨点,这两点同时体现在服装造型结构线的设计、结构塑型和工艺塑型设计集中点;凸点曲面表征方式为β(01)≈(ββ,σβ)。分别以BP点的胸部曲面和以肩胛骨点的背部曲面形态决定了二维样版基础形态,从而为个性化数字衣身样版的自动生成以及服装立体造型结构的平面化处理的实现,做好技术铺垫。

Relationship of Parameters Mapping Between 3D Garment and 2D Pattern based on E-MTM Technology

A mapping relationship equation was obtained between the convex point of the 3D surface and a simple cone being opened fiat, through analysis of the latter, and the angle mapping relationship from the basic 3D curve opening into the 2D plane was established. In the 3D morphology of digital fashion, convex point selection is mainly based on the clothing technology and modeling surface morphology, and fort the coat is mainly concentrated on the BP points of the chest section and the dorsal scapular point in the line of back width. The two are also the concentrated point for the design, in the clothing model structure line design, the plastic molding design and technology. The bump surface is characterized with/3（ol） ~ （/3~, 0＂8） . The 2D pattern is based respectively by the BP points on the chest surface and the scapular point on the back surface. It is good technical groundwork for the automatic generation of personalized clothing types and for the plane processing of 3D structure of digital clothing.
