摘要

Human-made structures' appearance depends on various aging phenomena, resulting in complex patterns that vary with time and the environment. Handling such complexity is important in computer graphics to improve virtual scenes' realism. Artists often do this work by hand. Their results are typically very good, but at the price of tediousness and a large amount of bibliographical research to place these patterns correctly on damaged objects. One way to tackle this problem is to provide new aging algorithms. A new model addresses salt-based aging, which leads to rich and common changes in appearance and plays an important part in the realism of scenes featuring stone structures and monuments. This model, based on physical behaviors and principles, replaces the simulation of complex physical formulations with ad hoc algorithms. It leads to plausible results, ultimately helping designers create aging patterns on affected objects.
