3D modelling of man-made objects is widely used in the cultural heritage sector, among others. It is relevant for its documentation, dissemination and preservation. Related to historical fabrics, weaves and weaving techniques are still mostly represented in forms of 2D graphics and textual descriptions. However, complex geometries are difficult to represent in such forms, hindering the way this legacy is transmitted to new generations. In this paper, we present the design and implementation of SILKNOW’s Virtual Loom, an interactive tool aimed to document, preserve and represent in interactive 3D forms historical weaves and weaving techniques of silk fabrics, dating from the 15th to the 19th centuries. To that end, our tool only requires an image of a historical fabric. Departing from this image, the tool automatically subtracts the design, and allows the user to apply different weaves and weaving techniques. In its current version, the tool embeds five traditional weaving techniques, 39 weaves and six types of yarns, which have been defined thanks to close collaboration of experts in computer graphics, art history and historical fabrics. Additionally, users can change the color of yarns and produce different 3D representations for a given fabric, which are interactive in real time. In this paper, we bring the details of the design and implementation of this tool, focusing on the input data, the strategy to process images, the 3D modelling of yarns, the definition of weaves and weaving techniques and the graphical user interface. In the results section, we show some examples of image analysis in order to subtract the design of historical fabrics, and then we provide 3D representations for all the considered weaving techniques, combining different types of yarns.

人工对象的3D建模已广泛用于文化遗产领域。它与其文档记录，分发和保存有关。与历史织物有关，编织和编织技术仍主要以2D图形和文本描述的形式表示。但是，复杂的几何形状很难以这种形式表示，这阻碍了这种遗产传给新一代的方式。在本文中，我们介绍了SILKNOW的Virtual Loom（虚拟织机）的设计和实现，这是一种交互式工具，旨在记录，保存和以交互式3D形式表示15至19世纪的丝绸织物的历史编织和编织技术。为此，我们的工具仅需要历史结构的图像。与这张图片不同的是，该工具会自动减去设计，并允许用户应用不同的编织和编织技术。在当前版本中，该工具嵌入了五种传统的编织技术，39种编织方法和六种类型的纱线，这要归功于计算机图形学，艺术史和历史织物专家的密切合作。此外，用户可以更改纱线的颜色并为给定的织物生成不同的3D表示，这些表示可以实时交互。在本文中，我们将详细介绍该工具的设计和实现，重点是输入数据，处理图像的策略，纱线的3D建模，组织的定义以及组织技术和图形用户界面。在结果部分中，我们展示了一些图像分析示例，以减去历史织物的设计，
