A Generation Method of Rust Aging Texture Considering Rust Spreading

Abstract

Rust is indispensable in order to synthesize realistic computer generated images. There are two kinds of rust. One is a kind of rust that iron was corroded actually, and another is a kind of rust that has been peeled from rusted iron surfaces and drifted flow of rainwater. We have developed a rust simulation system based on a cellular automaton that generates rust aging textures considering two kinds of rust. Several simulation results verify that two kinds of rust is effective to generate rust aging textures compared with real rust photos.
