Fabric mechanical parameters for 3D cloth simulation in apparel CAD: A systematic review

The primary objective of 3D virtual garment simulation within apparel CAD systems is to generate a highly realistic garment that accurately conform to the human body. However, due to the complexity of textile mechanics, variations in measurement technology, and the absence of standardized units of mechanical parameters, there exists considerable confusion surrounding the implementation of mechanical parameters in cloth simulation. Consequently, the accuracy of cloth simulation varies significantly among different apparel CAD systems. This research article aims to enhance the understanding of the fabric mechanical behaviors, measurement techniques, and parameters essential for cloth simulation. To achieve this objective, we first present a concise overview of current garment simulation in apparel CAD systems, focusing on the utilized mechanical parameters and methods for simulation accuracy evaluation. Subsequently, we delve into the fundamental principles of mechanical behavior, discussing measurement methodologies and proposing parameter unifications along with appropriate data ranges. Finally, we conduct a comprehensive review of cloth models and the requisite parameters, while also exploring simulation-based approaches for parameter estimation. This work provides crucial insights into fabric mechanical parameters essential for achieving accurate 3D virtual garment simulation. The findings and information presented herein can be effectively utilized to enhance the precision and fidelity of apparel CAD systems, thereby facilitating advancements in virtual garment design and production.
