基于云计算的针织物在线设计与三维仿真模型研究

It is a great significance to research the on-line design and 3D simulation system of knitting products based on the “Cloud Computing Technology (CCT)”. As the development of the internet technology, the traditional knitted fabric system cannot meet the needs of synchronal on-line design, rapid simulation for complicated patterns and real time 3D display. But all of these can be realized by utilizing the CCT. The online design and 3D simulation system of knitting products based on CCT is the inevitable trend of the integration of knitting technology and internet technology. In this project, the regulation of loop deformation will be researched and the mechanical structure model of knitted fabric will be built based on 3D spring-mass theory. The microscopic features of fabric structure will be studied and the structural model will be established based on the particle system theory. Then the garment model can be achieved by mathematical analysis and parametric design. Moreover, the data allocation principle among the servers under the parallel computing mode is discussed. The data allocation will be established as well. The problems including less sense of reality, low speed simulation for complicated patterns and non-real-time virtual display, can be well solved by implementing the on-line design and 3D simulation system of knitting products based on CCT. The research on this project will provide scientific support and theoretical foundation for knitted fabric simulation, virtual display and on-line fashion customization.
