Aging Simulation of 3D Models Based on Curvature Analysis and Color Transition

Aging simulation is one of the hot issues in the field of realistic rendering. This paper presents a method to simulate the aging phenomena of 3D models with the combination of curvature analysis and color transition. For a given 3D model, we analyze the curvature of each vertex, so as to determine its global geometrical features. And then on the assumption that different areas reflect diversely in the process of aging, we use curvature as a determining factor as we make color transition rules to simulate the visual effect of a certain aging phenomenon. The experimental results show that our method can achieve a satisfying sense of reality at a low time expense.
