Andrea Luongo: Being able to model the scattering of light by materials is crucial for realistic rendering of real-world objects, and an accurate rendering of material appearance is very important in nearly all design industries.
While in some cases a simple scattering model might be enough, for translucent materials (e.g. marble, cloth, skin, milk, snow, water) more sophisticated models are needed in order to account for the light that is scattered inside these objects (subsurface scattering).
In addition, translucent objects might have rough surfaces or might present small geometric features that are partly visible, and while algorithms have been developed for each of these aspects there is no practical method that properly accounts for their interaction when simulating light transport. We thus propose research with focus on finding a methodology for predictive rendering of such materials.
