摘要

当前钩针编织技术的自动化提供了许多可能性。为了充分利用这一潜力,不仅需要开发硬件,还需要开发能够设计新型机器钩针织物的方法。在手工钩针编织的情况下,根据3D形状钩针图案的自动生成方法已经在文献中提出。然而,目前提出的技术上最先进的钩针机原型可以从链排开始自动钩针编织平面织物。鉴于这种所谓的CroMat钩针机的局限性和操作,本文提出了一种根据二维凸多边形形成平面机钩针织物的工具。有了这个,表面可以划分成钩针使用镶嵌过程和数值优化。因此,遵循自动钩针编织过程的规则,以确保生成的图案的机器可制造性。织物的计算机模型被用作预览。此外,CroMat钩针机的定型可能性,特别是关于增加和减少针迹,提出并讨论了通过实例多边形形状的镶嵌优化。总的来说,该算法通过根据输入形状和CroMat钩针机原型的可能性自动生成有效的钩针图案,扩展了机器钩针织物设计工具箱。

Numerical Optimization of Polygon Tessellation for Generating Machine-producible Crochet Patterns
The automation of current crocheting technology offers many possibilities. To fully exploit this potential, it is necessary to develop not only hardware, but also methods that enable the design of novel machine-crocheted fabrics. In the case of manual crocheting, approaches for an automated generation of crochet patterns according to 3D shapes have already been presented in the literature. However, the most technically advanced crocheting machine prototype currently proposed automates the crocheting of flat fabrics starting from a chain row. Given the limitations and operation of this so-called CroMat crocheting machine, a tool for shaping flat machine-crocheted fabrics according to 2D convex polygons is presented here. With this, surfaces can be divided into crochet stitches using a tessellation process and numerical optimization. The rules of the automated crocheting process were thus followed to ensure the machine manufacturability of generated patterns. Computer models of the fabrics were used as previews. In addition, the shaping possibilities of the CroMat crocheting machine, in particular with respect to increase and decrease stitches, are presented and discussed by means of the tessellation optimization of exemplary polygon shapes. Generally speaking, the algorithm extends the toolbox for designing machine-crocheted fabrics through the automated generation of valid crochet patterns corresponding to input shapes and according to the possibilities of the CroMat crocheting machine prototype.
