“…Their research found that, while the crochet algorithm sequence is simple, the outcome product can be very complex. Çapunaman et al (2017) and Edelstein et al (Edelstein, 2022) developed computational design tools that extract crochet text instructions from the input of a 3D model. Seitz et al (2022) designed a pattern generator using visual language, and Guo et al (Guo et al, 2020) presented visual patterns using stitch meshes.…”

The past decade has seen a growing interest in the use of textiles in architecture, driven by advancements in digital knitting technology. However, while digital knitting machines have enabled the creation of 3D-shaped textiles, they still face limitations in terms of handling complex topologies, output scale, and material thickness. This study proposes crochet as an alternative to knitting in large-scale applications due to its ability to create seamless 3D shells. Although there have been significant advances in the computation of crochet instructions, placing it within the context of additive manufacturing, a digital fabrication method for volumetric crochet is still lacking. This paper offers a comprehensive overview of the recent history of computational tools utilized in fabricating continuous yarned 3D textiles together with an in-depth comparison to reveal the significant differences between knitting and crochet. It then proceeds to identify the relevant design attributes for a novel technology by analyzing hand gestures and toolpaths. Finally, the paper presents a novel digital fabrication device designed for large-scale crochet frameworks, which highlights the considerable advantages of crochet over other related fabrication methods. The proposed robotic device employs patented technology, which enables unprecedented fabrication capabilities in the field and opens new prospects for incorporating large-scale textiles in architecture.

“…The algorithm makes it possible to translate the surface sections into verbal descriptions, providing the crafter with text-based instructions. Edelstein et al (2022) offer an alternative solution for computational crochet instruction in relation to volumetric items, developing a different algorithm that extracts crochet text instructions based on a closed triangle mesh and a given seed point and stitch size. Guo et al (2020) create computerized 3D crochet models from tiles that demonstrate the different types of stitches as building blocks.…”

This paper uses the notion of fractal geometry to understand the underlying geometric rule behind the complex appearance of traditional Indian stepwells, taking the reference of Chand Baori, which is one of the most stunning and complex stepwells in India. Stepwells were mainly designed for religious, water conservation, and social purposes. This paper indicates those aspects in exploring the complex arrangement of the repetitive self-similar stair units in Chand Baori. The geometric quality of self-similar repetition resulting in a complex outcome can be systematically described by fractal geometry. Hence, this paper has adopted a fractal-based computational approach to model the Chand Baori stepwell, including a new stepwell design followed by the Sierpinski triangle, a canonical example of mathematical fractals. The fractal dimension method has been applied at the end to analyze the visual complexity of Chand Baori.

There is growing interest in incorporating digitally fabricated textiles into architecture. While most studies have addressed knitting and yarn winding, only a handful have involved crocheting. Crochet is a traditional handcraft that uses a hook to create fabric from a single yarn. Crochet is exceptional in its capability of creating seamless complex 3D shells. Despite significant progress attained in the computation of crocheting instructions, which positions it in an additive manufacturing context, a rigorous fabrication solution for crochet is still lacking. The present study examines the possibilities of applying additive manufacturing principles for adapting crochet from handcraft into digital fabrication using a robotic arm. The experimental phase focuses on toolpath design, targeting the primary steps involved in the performance of crochet stitches using a robotic arm. Initial stages include a manual scheme, using 3D-scanned pre-prepared cloth as a foundation for path design, and recording the crochet hook path in digital format. This study defines the first steps in transitioning crochet from handcraft to a robotic process and establishes the method's feasibility based on the computational design of the tool path. Robotic crochet enables the production of remarkably complex seamless 3D textiles in large-scale formats and opens the field to architectural applications.
