Design e Desenvolvimento de Produto 3D




O universo 3D é realmente fascinante, é extremamente excitante imaginar o que podemos fazer com essa tecnologia e suas aplicações na vida real, como melhorar as suas capacidades. Neste momento, os desafios no processo tornam-se também pontos de inspiração. Esse espaço destina-se a divulgar tudo que esta acontecendo sobre vestuário virtual. Para aqueles que trabalham com Designer & Desenvolvimento de Produtos de Moda e que se utilizam das ferramentas mais avançadas da realidade virtual. Para aqueles que não fazem a mínima idéia do que seja isso mas gostariam de fazer parte se apressem, a realidade virtual é o futuro. Eu espero em breve estar postando as minhas criações em 3D, eu utilizo o Blender que é um software de código aberto, não é tão simples, mas tenho fé que chegarei lá. Quem tiver alguma sugestão meu email annahelena@hotmail.com.br . Sejam Bem vindos ao universo 3D!

Design de vestuário 3D

A survey on CAD methods in 3D garment design
 Yong-Jin Liua, Dong-Liang Zhangb,Matthew Ming-Fai Yuenc -Department of Mechanical Engineering, The Hong Kong University of Science and Technology

Abstract

With the advance in virtual reality applications, garment industry has strived for new developments. This paper reviews state-of-the-art CAD methods in 3D garment design. A large range of techniques are selected and organized into several key modules which form the core of a 3D garment design technology platform. In each module, basic techniques are presented first. Then advanced developments are systematically discussed and commented. The selected key modules – digital human modeling, 3D garment design and modification, numerical integration of draping, 2D pattern generation, geometric details modeling, parallel computation and GPU acceleration – are discussed in turn. Major challenges and solutions that have been addressed over the years are discussed. Finally, some of the ensuing challenges in 3D garment CAD technologies are outlined.
