3.1 Introduction

The composition of detailed textures, facilitating weathered and aged looks, is

an everyday task for content artists in game and movie production. Examples of

aged scenes are shown in Figure 3.1. In the process of meticulously editing tex-

tures, each inaccuracy or later change in the scenery can cause implausibility and

quickly break the immersion. Therefore, interactively steerable, automatic simu-

lations that favor the plausibility of aging effects, caused by interacting objects,

e.g., dripping of rust, are vitally needed. This chapter describ ...
