Modelling deposition of surface texture

A class of surfaces formed by deposition are analysed and modelled. The surface derivative fields are estimated using photometric stereo and their spectra modelled. A published technique that uses the repeated addition of a primitive to simulate the surface is tested. The quality of the model is assessed by comparing simulated images with the originals. When used with photometric stereo and a surface spectrum model the technique is useful for modelling the appearance of the surface throughout the deposition process.
