Patent number: 10373373Abstract: Systems and methods are provided for enabling the reduction of the time required to simulate a garment fitting onto a destination body shape with high visual quality, while also offering high performance and accuracy. The embodiments described herein include, for example, caching of source body meshes having a geometric difference with a destination body mesh that is within a predefined threshold. At least one of the cached source body meshes is selected, based, at least in part, on a wearable measurement range of the garment. For each of the selected cached source body meshes, a deformable object mesh representing the garment is generated, wherein the generating is based, at least in part, on the selected cached source body mesh. A source body mesh having body measurements that most closely match the body measurements of the destination body mesh is identified from among the selected cached source body meshes.Type: GrantFiled: November 7, 2017Date of Patent: August 6, 2019Assignee: STYLEME LIMITEDInventors: Jonathan Zhan Hua Leong, Ying-Hung Chen, Tsung-Chih Tsai
