Key Designs in Implementing Online 3D Virtual Garment Try-On System

Abstract

Online 3D Virtual Garment Try-on System is deeply needed and would be quite popular if we could improve its accuracy, effect, and user experience. In order to achieve these goals, we propose several key designs in implementing it. In this paper, we discuss the system architecture design at first. Then we introduce a simple but effective method to model 3D body prototypes. Based on models in Poser software, we segment them into layers and then do triangularizition to get triangular surfaces. As for garment modeling based on Spring-Mass model and physical try-on simulation, we propose a novel method based on uniform grid to detect collision. Store references of triangular surfaces into grids that they occupied and then calculate which grids a moving line of mass go through. Get triangular surfaces in these grids out and then judge whether the moving line intersects with them. It achieved fast detection in around 0.1% of time consuming by using linear searching. The performances of body modeling and try-on simulation are satisfying, and real-time responses could be achieved because of less complex computation and light-scale data transformation.
