Development of interactive Kansei products design system

当前的计算机技术对改善日常生产系统具有很大的潜力。在这项研究中，我们开发了一个由动态人体模型、三维服装模型库和虚拟试衣仿真组成的交互式三维服装设计系统。该系统使用户可以随心所欲地设计各种服装，并用计算机中的虚拟试衣模拟取代了通常服装生产中的试衣和试衣过程。它可以减少试制过程中的浪费和时间，在服装行业和基于计算机网络的电子商务中具有一定的实用价值。(1)建立了人体骨骼模型，该模型决定了构成人体形状的姿态和表面模型。(2)建立了服装基本体型数据库，并利用该数据库建立了服装几何模型。(3)开发了包括服装体型模型、细节形状和布料纹理的交互式三维CAD系统。通过本系统，设计了。普通用户在没有服装技术知识的情况下，也可以在三维环境中穿衣服。此外，还可以通过存储到数据库中的布料纹理的变化来表达材料的感觉。(4)开发了由设计的三维服装形状形成生产所需的服装图案信息的系统。(5)开发了将人体模型与服装设计信息相结合的动态服装仿真系统。利用粒子模型，开发了考虑织物力学性能的真实感服装仿真系统。

Current computer technology has great potentiality to improve the usual production system. In this study, we developed an interactive 3-D apparel design system consisting of a dynamic human body model, a 3-D clothing model database, and virtual fitting simulation. This system enables users to design various kinds of clothes as they please, furthermore, the sample making and fitting process in the usual apparel production is also replaced by virtual fitting simulation in the computer. It can reduce waste and time in trial production and will be useful in apparel industry and electronic commerce based on computer network.( 1 ) We built human skeleton model that decides the posture and surface model that forms human body shape. This model can express a personal figure by using measuring information.( 2 ) A database of basic clothes shapes by which the geometric model of clothes can be construct are made,.( 3 ) An interactive 3 dimensional CAD system was developed, which includes clothes shape model, detail shapes and cloth textures. By this system, design of. clothes can be possible in 3 dimensions environment by the general user even they have no technical knowledge of clothes. Furthermore, the feel of material can be expressed by a change of cloth texture stored to the database.( 4 ) A system which formed dress pattern informalion necessary for the production from designed 3 dimensional clothes shape was developed.( 5 ) We developed dynamic dressing simulation system that combined the human body model with clothes design information. User can confirm wearing state of clothes designed by this system.( 6 ) Using particle model, realistic clothes simulation system considering mechanical properties of fabrics was also developed.
