It is a matter not only of generating photo-realistic images in 3D garment simulations, but also of making reliable predictions about the physical behavior of textile materials in order to achieve realistic outcomes. The prerequisite for 3D garment simulation is the correct application of standardized simulation programs, which is rarely accomplished in practice because the providers of 3D simulation software do not disclose their simulation algorithms, making accurate analysis difficult. In this study, an objective image comparison is carried out using the VStitcher simulation program as an example, which allows an assessment of the value of the relevant material parameters. A drape test is used as a validation method and the drape coefficient is calculated. Depending on the material and parameter settings, drape coefficients between 0.1 and 10\% and between 0.7 and 70\% are determined. By modifying the bending stiffness, the drape coefficient increases the most. By systematically varying and comparing these parameters, a deeper understanding of their influence can be obtained. The most significant effect on the drape coefficient (DC) is seen with increased bending stiffness, while changes in thickness, elongation, and shear stiffness have a minimal effect. Increased fabric thickness has a greater effect on appearance than on deformation. The digital parameters affect the simulation in much the same way as the physical textile parameters affect the real material. With VStitcher, the desired fabric changes are more effectively achieved by adjusting the bending stiffness and mass per area, while changes in thickness, elongation, and shear stiffness have little effect.}, subject = {drapability}, language = {en} }
