Further discussions on user interface decisions, the impact of the atlas resolution
on memory consumption and visual quality, as well as texture seam handling can
be found in our paper [Gunther et al. 12].
3.6 Conclusions
In this chapter, we presented an interactive material aging simulation based on
gammaton tracing on the GPU. We used a simple yet powerful set of rules to
obtain the most common aging effects, including dirt, rust, organic, and water
