Synthesis of material drying history

We consider the problem of the spatio-temporal variations in material appearance due to the wetting and drying of materials. We conducted a series of experiments that capture the appearance history of surfaces drying. We reduce this history to two parameters that control the shape of a drying curve. We relate these drying parameters to the shape of the original wetted area and the surface geometry. Using these relationships, we generate new time-varying spatial patterns of drying on synthetic shapes.
