Interactive Cloth Manipulation With Multi-Touch Control

We present an interactive system for intuitive manipulation of dynamic cloth using multi-touch technology. The system consists of two main modes that can be toggled anytime, namely cloth creation mode and cloth manipulation mode. In cloth creation mode, the user creates pieces of cloth by drawing each desired shape directly onto the scene using simple swipe gestures. The system automatically generates the best-fit cloth mesh from each drawn shape and renders each cloth on the scene. When cloth manipulation mode is selected, the user can manipulate cloth using a multi-touch pad by placing various fingers at desired locations of the cloth and moving them. Internally, the system seeks the nearest underlying cloth particles under each finger and sticks them to each active finger, while allowing the remaining cloth particles to readjust and move dynamically according to the underlying particle simulation. Our two key interaction techniques, sticky fingers and pinch-lifting, along with the use of Verlet integration and iterative constraint satisfaction, make it possible to control multiple cloth points simultaneously and in varying velocities, allowing the user to intuitively produce a range of complex cloth manipulations such as pinching, draping, tearing and folding.
