Mobile devices' GPUs in cloth dynamics simulation

The realistic simulation of cloths is nowadays a key to produce good-quality, authentic graphical visualizations of various cloth, such as characters garment elements, flags or curtains. This can be computationally expensive, more and more as number of particles, which cloth is divided into, increases. The solution to this matter was to use GPU (Graphic Processing Unit) and perform all calculations on this device. On PC platform, this technique proved to be much faster than the standard CPU approach. The main purpose of this work is to check whether this solution could also be introduced on the mobile devices. In this paper, we developed fast vertex optimization methods for dynamic cloth in mobile GPU units. Additionally we develop a user interface which providing new ways of user interaction with a cloth dynamics simulation on mobile devices.
