Impact of avatar type and surface characteristics on garment fit in 3D simulation

The development of digital technologies has enabled the analysis of the behavior of clothing products in a virtual environment using 3D simulation. One of the important factors in these simulations is the digital avatar, whose characteristics can affect the interaction between clothing and the body. The aim of this work was to examine the influence of the avatar type and its surface characteristics on the clothing fit and stress distribution during 3D simulation. The simulation was conducted in the Browzwear V-Stitcher software on a dress model made of 100% cotton rib knit (2×2 rib) and interlock. The analysis included two types of avatars (hard and soft Olivia) and three types of avatar surfaces (human, plastic and fabric). The results show that the highest stress values are recorded in the chest area, while the differences between the avatar surfaces are relatively small. At the same time, it was observed that the deformability of the soft avatar affects the contact between clothing and the body and allows for a more natural fall and draping of the material compared to a rigid avatar.
