Knitting a 3D Model

A knitted animal is made of a closed surface consisting of several knitted patches knitted out of yarn and stuffed with cotton ( Fig. 1 ). We introduce a system to create a knitting pattern from a given 3D surface model (mainly designed for rotund animal models). A knitting pattern is an instructional diagram describing how to knit yarn to obtain a desired shape. Since the creation of knitting patterns requires special skill, this is difficult for nonprofessionals. Our system automates the process and allows anyone to obtain his or her original knitting patterns from a 3D model. The system first covers the surface of the model with parallel winding strips of constant width. The system then samples the strip at constant intervals to convert it into a knitting pattern. The result is presented in a standard visual format so that the user can easily refer it during actual knitting. We show several examples of knitted animals created using the system.

一个针织动物是由一个封闭的表面构成，这个表面由若干用纱线织成的针织片组成，并填充有棉花（图1）。我们引入了一个系统，用于从给定的三维表面模型（主要是为圆润的动物模型设计的）创建针织图案。针织图案是一种说明图，描述如何编织纱线以获得所需的形状。由于创建针织图案需要特殊技能，这对非专业人员来说是困难的。我们的系统使这个过程自动化，并允许任何人从一个三维模型中获得他或她自己原创的针织图案。该系统首先用等宽的平行缠绕条覆盖模型的表面。然后系统以固定的间隔对条带进行采样，将其转换为针织图案。结果以标准的可视化格式呈现，以便用户在实际针织过程中可以轻松参考。我们展示了几个使用该系统制作的针织动物的例子。
