abstract = {We present a viscous paint model for use in an interactive
painting system based on the well-known Stokes’ equations for
viscous flow. Our method is, to our knowledge, the first
unconditionally stable numerical method that treats viscous fluid
with a free surface boundary. We have also developed a real-time
implementation of the Kubelka-Munk reflectance model for pigment
mixing, compositing and rendering entirely on graphics hardware,
using programmable fragment shading capabilities. We have
integrated our paint model with a prototype painting system, which
demonstrates the model’s effectiveness in rendering viscous paint
and capturing a thick, impasto-like style of painting. Several
users have tested our prototype system and were able to start
creating original art work in an intuitive manner not possible
with the existing techniques in commercial systems.},
