Abstract



We propose visually simulating wood aging by microorganisms using an ant colony optimization algorithm to generate wood aging patterns. Ants deposit pheromone similar to termites and wood deterioration caused by termites is simulated using this algorithm. Patterns generated by this algorithm resemble many pattern in nature, meaning ant paths are representative of worm paths and ant pheromones are representative of microorganism growth. We demonstrate the effectiveness of this technique in experiments.
