Fitting 3D garment models onto individual human models

Designing an elegant 3D virtual garment model for a 3D virtual human model is labor-intensive, because most existing garment models are custom-made for a specific human model and cannot be easily reused for other individuals. In this paper, we propose a novel method for fitting a given 3D garment model onto human models of various body shapes and poses. The fitting is accomplished by deforming the garment mesh to match the shapes of the human models by using a combination of the following: skeleton-driven volumetric deformation, garment–human shape similarity matching and evaluation, the constraints of garment–human contact, and garment–human ease allowance. Experiments show that our approach performs very well and has the potential to be used in the garment design industry.

Fitting a garment onto a human model: (a) Human model H with its skeleton. (b) Garment model G. (c) Form G's skeleton by adjusting the duplicated human skeleton, which is then embedded inside G. (d) Tetrahedral mesh T containing G. (e) Deform T by aligning G's skeleton with H's. (f) Decode the new mesh G from deformed T. (g) Adjusting G with garment–human contact constraints. (h) Resolve the penetrations between G and H.Figure optionsDownload high-quality image (64 K)Download as PowerPoint slideResearch Highlights
