Abstract:
For centuries, artists have used traditional media and tools to express their thoughts and feelings creatively. More recently there has been a growing interest in non-photorealistic rendering and in recreating these media faithfully on a computer. Some of the most popular materials used in painting are acrylics and oils, and a key feature of these paints is that they can be very viscous and can be applied very thickly to create an impasto style. We have created a digital impasto painting medium based on the Stokes’ equations for viscous flow, and a hardware implementation of the Kubelka Munk equations for accurate color mixing and compositing of pigmented materials like paint. To our knowledge this is the first work which has attempted to simulate the properties of viscous paint by solving these physical equations directly.
