Converting to reusable garment model

Converting to reusable garment model Purpose – Reusability of geometric model is of essential importance in garment simulation since in reality, the same garment dressed on different human bodies will exhibit different draping results. Due to the multiplicity of a garment which can be dressed on various human bodies, it is necessary to reuse a given geometrical garment model in the cyberspace, the purpose of this paper is to explore this. This requires the technique of converting a geometrical model to a physically‐based model to predict the dressing result. Design/methodology/approach – In this paper, a 3D garment model obtained from range data scanning is reconstructed as a mass‐spring system driven by the first order backward Euler integrator. The penetration of dressing onto the given avatars is compensated through an AABB accelerated collision detection and response scheme. Findings – This paper implements efficient techniques resolving intersection for cloth simulation. Two stages are selected for handling the collision. The first stage is trying to prevent collision from happening in the first stage, and the second stage is to deal with actual intersections. This two‐stage approach eliminates almost all collision in the first stage, leaving only a few collisions for the second stage. Results obtained with this approach, in the case of dressing garments on different avatars are presented and validate the conversion method from geometric model to deformable one. Originality/value – The experimental results validate this method as a useful and effective approach to exhibit draping behavior on various human body shapes accordingly. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Clothing Science and Technology Emerald Publishing

Abstract

Purpose – Reusability of geometric model is of essential importance in garment simulation since in reality, the same garment dressed on different human bodies will exhibit different draping results. Due to the multiplicity of a garment which can be dressed on various human bodies, it is necessary to reuse a given geometrical garment model in the cyberspace, the purpose of this paper is to explore this. This requires the technique of converting a geometrical model to a physically‐based model to predict the dressing result. Design/methodology/approach – In this paper, a 3D garment model obtained from range data scanning is reconstructed as a mass‐spring system driven by the first order backward Euler integrator. The penetration of dressing onto the given avatars is compensated through an AABB accelerated collision detection and response scheme. Findings – This paper implements efficient techniques resolving intersection for cloth simulation. Two stages are selected for handling the collision. The first stage is trying to prevent collision from happening in the first stage, and the second stage is to deal with actual intersections. This two‐stage approach eliminates almost all collision in the first stage, leaving only a few collisions for the second stage. Results obtained with this approach, in the case of dressing garments on different avatars are presented and validate the conversion method from geometric model to deformable one. Originality/value – The experimental results validate this method as a useful and effective approach to exhibit draping behavior on various human body shapes accordingly.
