Abstract:
A method for producing a watercolor simulation that represents at least one wash applied to paper, each wash including at least one pigment dispersed in a fluid, comprising the steps of:(a) providing a fluid model that includes a plurality of layers for each wash included in the watercolor simulation, wherein said plurality of layers comprise:(i) a shallow fluid layer in which the wash flows above a surface of the paper;(ii) a pigment deposition layer where a pigment is adsorbed and desorbed by the paper; and(iii) a capillary layer within the paper in which the wash is diffused by a capillary action;(b) as a function of a plurality of predefined parameters and in accord with the fluid model, specifying how each wash flows over the paper to determine quantities of each pigment(c) applying an optical composite model to render the watercolor simulation as a function of optical characteristics of each pigment and as a function of the quantities of each pigment deposited at the plurality of discrete spatial locations on the paper.
