Abstract

Secular change is an important factor to produce realistic computer graphics (CG) images. Rust generated over time on metals is an example of such secular change. The appearance of rust depends on the type of metal, on water adherence by rain or sea water, on the quantity of dissolved oxygen in water, and on effects of water flows. To our knowledge, there are no simulation models of rust that take into account the relevant chemical reaction processes. In the method proposed here, we perform a fluid simulation, calculate the water adherence and flow using three-dimensional models, and calculate the progression of corrosion from sites of adherence. This corrosion simulation takes into account conditions such as the amount of adherence and the relevant chemical reaction processes. As a result, we show that the mass loss for iron is close to the theoretical value, and that CG images are similar to those of actual rust.
