Donner and Jensen 2006 later introduce a two-layer model that still gives convincing results. We show a similar comparison in Figure 14-11, in Section 14.4.3, using our real-time system, which is capable of modeling this multilayer scattering. Donner and Jensen 2005 demonstrate that a single-layer model is insufficient and show the improvement obtained from using a three-layer model. Now you can make your Sims suffer from breakouts and help them experience skin problems real humans face, with this realistic acne mod. Simulating scattering at this complexity is probably excessive, but realistic rendering requires modeling at least two distinct layers below the oily layer responsible for specular reflection. Real skin is even more complex medically, the epidermis alone is considered to contain five distinct layers (Poirer 2004). The Light skin has two tone ramps, and the Tan skin has four tone ramps. 2 high quality texture2048x2048 non-defalut skin. Graphics researchers have produced very detailed models that describe optical scattering in skin using as many as five separate layers (Krishnaswamy and Baranoski 2004). This set contains: 1 normal default skin. Complicating the process further, multiple layers within the skin actually absorb and scatter light differently, as shown in Figure 14-4.
