针织提供了在单片织物内创建3D几何形状的可能性，包括不可展开的表面，而无需剪裁或缝合。为了创建CNC针织物，需要2D逐行指令形式的针织图案。目前，这些针织图案是基于非可展几何形状的展开表面、基元或合理化方案直接在2D中设计的。创建这样的图案是耗时的，并且对于不基于已知基元的几何体是非常困难的。本文提出了一种自动生成给定的三维几何形状的针织图案的方法。从3D网格开始，用户定义编织方向和与给定机器对应的所需线圈参数。对网格几何形状进行轮廓化，随后使用定义的线圈高度进行采样。基于轮廓的采样，生成相应的路线，并且包括所谓的短行。然后，使用定义的环宽度对路线进行采样，以创建最终拓扑。这变成了一个2D针织图案的形式，代表线圈课程的正方形。该文件显示了两个例子的方法适用于非可展曲面：四分之一球和四价节点。
Knitting offers the possibility of creating 3D geometries, including non-developable surfaces, within a single piece of fabric without the necessity of tailoring or stitching. To create a CNC-knitted fabric, a knitting pattern is needed in the form of 2D line-by-line instructions. Currently, these knitting patterns are designed directly in 2D based on developed surfaces, primitives or rationalised schemes for non-developable geometries. Creating such patterns is time-consuming and very difficult for geometries not based on known primitives. This paper presents an approach for the automated generation of knitting patterns for a given 3D geometry. Starting from a 3D mesh, the user defines a knitting direction and the desired loop parameters corresponding to a given machine. The mesh geometry is contoured and subsequently sampled using the defined loop height. Based on the sampling of the contours the corresponding courses are generated and the so-called short-rows are included. The courses are then sampled with the defined loop width for creating the final topology. This is turned into a 2D knitting pattern in the form of squares representing loops course by course. The paper shows two examples of the approach applied to non-developable surfaces: a quarter sphere and a four-valent node.
