LaTeX Abstract:In this thesis, we cover three scenarios that violate common simplifying assumptions about the nature of light transport.

We begin with the first ingredient to any 3D rendering: a geometry model. Most 3D scanners require the object-of-interest to show diffuse reflectance. The further a material deviates from the Lambertian model, the more likely these setups are to produce corrupted results. By placing a traditional laser scanning setup in a participating (in particular, fluorescent) medium, we have built a light sheet scanner that delivers robust results for a wide range of materials, including glass.

Further investigating the phenomenon of fluorescence, we notice that, despite its ubiquity, it has received moderate attention in computer graphics. In particular, to date no data-driven reflectance models of fluorescent materials have been available. To describe the wavelength-shifting reflectance of fluorescent materials, we define the bispectral bidirectional reflectance and reradiation distribution function (BRRDF), for which we introduce an image-based measurement setup as well as an effcient acquisition scheme.

Finally, we envision a computer display that shows materials instead of colours, and present a prototypical device that can exhibit anisotropic reflectance distributions similar to com-
mon models in computer graphics.
