Abstract: A computer-implemented method for designing an avatar with at least one garment, the method comprising the steps of: S1) providing a digital model of an avatar comprising a skeleton (SN) and a skin (SK) covering the skeleton; S2) providing a digital model of a garment (GT) comprising a mesh having a plurality of vertex (vg1-vg7) connected by edges defining faces, each vertex being associated to at least one bone (B1, B2) of the skeleton of the avatar through a respective weighting coefficient; S3) associating a displacement direction (dd1-dd7) to each vertex of the garment, said displacement direction depending on the skeleton and on said weighting coefficients; and S4) detecting collisions between the skin of the avatar and the garment and, whenever a collision is detected, displacing a vertex of the garment away from the skeleton of the avatar along said displacement direction. A computer program product, a computer-readable data storage means and a Computer Aided Design system for carrying out such a method, and an avatar wearing at least one garment, suitable to be designed by such a method.

Abstract translation: 一种用于设计具有至少一件衣服的化身的计算机实现的方法，所述方法包括以下步骤：S1）提供包含骨架（SN）和覆盖所述骨架的皮肤（SK）的化身的数字模型; S2）提供衣服（GT）的数字模型，其包括具有通过限定面部的边缘连接的多个顶点（vg1-vg7）的网格，每个顶点与所述骨架的至少一个骨骼（B1，B2）相关联 化身通过各自的加权系数; S3）将位移方向（dd1-dd7）与衣服的每个顶点相关联，所述位移方向取决于骨架和所述加权系数; 以及S4）检测化身的皮肤和服装之间的碰撞，并且每当检测到碰撞时，沿着所述位移方向将服装的顶点从化身的骨架移开离开化身的骨架。 用于执行这种方法的计算机程序产品，计算机可读数据存储装置和计算机辅助设计系统，以及穿着至少一件衣服的化身，适合于通过这种方法设计。
