A Viscous Paint Model for Interactive Applications


We present a novel viscous fluid model for use in real-time simulation applications, such as interactive painting systems, based on the well-known Stokes' equations for viscous flow. Our method is perhaps the first unconditionally stable numerical method that treats viscous fluid with a free surface boundary. We have integrated our fluid model with a prototype painting system, which demonstrates the model's effectiveness in animating viscous fluid flow and capturing a thick, impasto-like style of painting.
