Computer Graphics Techniques for Capturing and Rendering the Appearance of Aging Materials



Abstract: Computer graphics photorealistic rendering techniques are capable of rendering images that predict the appearance of yet to be manufactured objects. A challenge in computer graphics realism is creating the digital models of shape, materials, and lighting that are required for such rendering. Models for materials that have been aged by weathering or usage are difficult to produce. A recent trend in computer graphics is to attempt to capture aged materials in a form that allows them to be applied to arbitrary new shapes. We present the techniques used for capture and some sample results. Current techniques can be applied to various types of visual simulation, and we outline some future potential applications of rendering aged materials.
