Abstract: In the field of intelligent patchwork, despite existing research on the organization of quilting fabric databases and rapid fabric selection, research on the rapid digital design of quilting patterns is still lacking. This study aims to develop a tool for rapidly designing patchwork patterns with similar geometric shapes, incorporating intelligence into traditional patchwork design to fulfill the demand for personalized patchwork designs, and improving design efficiency and creativity.
Utilizing parametric modeling and intelligent design techniques, this study rapidly created homomorphic patchwork patterns. A feature-based parametric design model was established to store geometric features, coordinates, and filling styles. Specific design parameters were abstracted into design variables, with value range constraints and initial values specified for each. The constructed parametric model allows for observation and iterative adjustments of design changes by modifying the values of design variables, providing flexible control over the design process and achieving efficient and controllable parametric design. The innovation of this study lies in applying parametric modeling and intelligent design techniques to traditional patchwork design, providing flexible control over the design process, and realizing efficient and controllable parametric design. The study investigated the parametric design model of patchwork patterns using design variable methods and used matrix mathematical models to represent the patterns, allowing for flexible control over the design variables of patchwork patterns. Within the design platform, this study rapidly achieved the parametric design of patchwork patterns. The platform supports users in selecting pattern types, inputting parameters, and viewing real-time design outputs. The core design component uses Canvas rendered with Pixi.js for interactive, real-time design. Additionally, the platform utilized Pinia as a local data cache-sharing repository, combined with automatic cloud data caching technology, optimizing data processing. A decoupled software architecture was used, leveraging the Vue3 and FastAPI frameworks for front-end and back-end development, enhancing development efficiency and user experience. The design interface includes three modules: pattern selection, attribute configuration, and style design, supporting dynamic parameter adjustment and real-time preview, reducing manual design efforts and enhancing the realism of the displayed outputs. Overall, this study has successfully developed a rapid design tool that modernizes the traditional fabric design process, enhancing design efficiency and creativity.
The outcomes of this study provide innovative tools and platform support for the rapid design of homomorphic patchwork patterns, meeting the demand for personalized fabric patterns. Future work can explore further applications and improvements to this framework to further enhance design efficiency and creativity.
