Chapter 3. Image-Synthesis Context
Different image-synthesis frameworks can be used to realistically render the appearance of human skin. They share, however, a similar pipeline structure (Figure 3.1). The stages of this pipeline include, but are not limited to, the geometrical representation of skin surfaces, the spectral sampling of light sources, the modeling of (local) light and skin interactions, the computation of environmental (global) light transfers, and the conversion of the resulting radiometric quantities into appearance attributes (e.g., color and glossiness).

In this chapter, we provide an overview on how the skin-lighting models examined in this ...
