Simulating Watercolour Painting

In this paper I describe the research and development for a real-time watercolour painting program. I present my research into related areas of interest, such as fluid dynamics, cellular automata and Kubelka-Munk theory. I look closely at two existing systems for simulating the properties of watercolour paints, and assess their possible applicability to real- time painting. I go on to develop two programs to test my ideas, and provide the design for a third that should solve the problems encountered with previous implementations.
