Appearance reproduction is an important aspect of 3D printing. Current color reproduction
systems use halftoning methods that create colors through a spatial combination of different …

The four-flux model is a method to solve light radiative-transfer problems in planar, possibly
multilayer structures. The light fluxes are modeled as two collimated and two diffuse beams …

We propose a compositional model for predicting the reflectance and the transmittance of
multilayer specimens composed of layers having possibly distinct refractive indices. The …

Of our five senses, it is estimated that vision provides almost 80% of the total input to the
brain related to our environment. This means that the amount of data passing through our …

The Lambertian model for diffuse reflection is widely used for the sake of its simplicity.
Nevertheless, this model is known to be inaccurate in describing a lot of real-world objects …

Strongly scattering supports coated with thick transparent medium display a bright halo with
a characteristic ring shape when illuminated in one point by a thin pencil of light. The halo …

We investigate the optical phenomenon responsible for the colored shine that sometimes
appears at the surface of ink layers in the specular direction, often called bronzing or gloss …

When a transparency printed with a first halftone color is deposited on top of a paper printed
with a second halftone color, we obtain a third color that we are able to predict in both …

We introduce a model allowing convenient calculation of the spectral reflectance and
transmittance of duplex prints. It is based on flux transfer matrices and enables retrieving …

The color of a surface structured at the mesoscopic scale differs from the one of a flat surface
of the same material because of the light inter-reflections taking place in the concavities of …
