Abstract: We present a real-time, physics-based framework to simulate porous, deformable materials and interactive tools with haptic feedback that can reshape them. In order to allow the material to be moulded nonhomogeneously, we propose an algorithm to change the material properties of the object depending on its water content. To enable stable visual and haptic feedback at interactive rates, we implement a multi-resolution, multi-timescale solution. We test our model for physical consistency, accuracy, interactivity and appeal through a user study and quantitative performance evaluation.
