Abstract

The use of simulation to apply virtual paint to virtual paper can take many forms ranging from Pollock-style drip paintings to simulated watercolor techniques to paint program airbrush tools. We use physically based modeling to simulate streams of encapsulated paint particles. When set in motion, particles are subject to an artificial gravity, and melt when they contact a virtual canvas. By incorporating algorithmic art methods, and by taking advantage of the scattering effects that result from particle collisions, we explain how we created a series of color studies using colliding particles organized into carefully orchestrated streams of simulated paint droplets.
