纬编针织物组织三维仿真系统的设计与实现

Design and Implementation of 3D Simulation System of Weft Knitted Fabric Structures

针对目前纬编CAD系统大多采用二维仿真模式,不能体现织物立体效果的问题,本文以Visual C++和OpenGL为开发工具,设计开发了一种新型的纬编针织物组织三维仿真系统。阐述系统总体设计方法,包括框架结构、逻辑模型、开发工具、运行环境等。系统功能模块包括文件模块、视图模块、基本组织仿真模块和花色组织仿真模块等。该系统通过交互式输入花型参数、线圈参数、纱线参数,可以进行主要纬编组织三维仿真设计,还可以对组织进行放缩,并从不同角度观察织物结构;通过将织物仿真图与真实织物进行对比,发现该三维仿真系统的织物仿真效果明显优于二维仿真方式。

In terms of the problem of the present weft CAD system mostly using the model of two-dimensional simulation, and not achieving the three-dimensional effect of fabric, the paper designs and develops a new type of 3D simulation system of weft knitting fabric structures based on Visual C＋＋ and OpenGL development tools. It ex- pounds the overall design method of system, including system structure, logical model, development tools, runtime environment and so on. It also indicates that the function modules of system includes file module, views module, basic stitch simulation module and fancy stitch simulation module. The results show that the system can realize the major three-dimensional simulation design for weft knitting stitch by inputting pattern parameters, loop parameters and yarn parameters interactively, zoom in the stitch and observe the fabric structure from different angles; the fabric simulation effect of 3D simulation system is better than 2D emulation mode by companng the real fabric with the fabric simulation diagram.
