The mechanical deformation behavior of textiles can be divided into drape and drapability, both of which affect the overall appearance, aesthetics, and fit of garments. In garment simulation, this behavior must be reproduced as realistically as possible in order to provide a meaningful evaluation of the design and construction. Understanding how material parameters impact simulation results is crucial. By systematically varying and comparing material parameters, a deeper understanding of their influence can be gained, leading to more accurate simulations and better insights into the real-world behavior of the fabric. This study investigates and compares real and simulated textile falls. The drop coefficient serves as a numerical measure. Three cotton fabrics of varying weave constructions are thoroughly studied. Real textile drop according to Cusick and simulated textile drop are determined in two experiments using the VStitcher simulation program. A subjective image comparison evaluates the simulation quality, analyzing material parameter variations step by step. The results indicate that bending in the VStitcher simulation program significantly influences the virtual textile behavior and simulation outcomes. Moreover, the study highlights the potential deviations from actual draping behavior, particularly with regard to the anisotropy of the material. Further research should focus on developing simulation algorithms that take into account the anisotropic nature of textiles, ensuring that the simulations accurately represent the behavior of the fabric in different directions. This study highlights the notable deviation between simulated and real fabric behavior when adjusting material parameters in a 3D representation, which is crucial for fit analysis, optimization, and 3D image generation. Establishing standardized data acquisition methods and accessible simulation algorithms is essential for advancing the adoption of simulation in the garment industry. A coordinated effort to define these standards and best practices will facilitate collaboration and enable more accurate and reliable simulations across different organizations and platforms.
