Optimization of virtual fabric draping effect based on VStitcher

To optimize the virtual fabric drape effect in VStitcher, drape experiments on 38 selected fabric samples were conducted. A comparative analysis was performed by measuring 8 drape indicators for both virtual and physical fabrics to quantify their discrepancies. Subsequently, the physical properties of the virtual fabrics were systematically adjusted to align their drape behavior with that of their real-world counterparts. Using the least squares, a fitting analysis was conducted on the physical properties before and after adjustment, leading to the establishment of an optimization model for virtual fabric physical properties. To validate the model, three additional fabric samples were randomly selected for testing. The results demonstrate that the relative error between the drape indicators of the optimized virtual fabrics and the physical fabrics is within 5%. This confirms the effectiveness and accuracy of the proposed model in enhancing the realism of virtual fabric drape simulation.
