This paper implements an appearance rendering workflow using the iccMAX architecture with the aim of reproducing the directional appearance of surface colours on a display. In previous work, the prints were measured bidirectionally using an image-based measurement setup, and the bidirectional reflectance distribution function of the materials was estimated using the well-established Ward reflectance model. This function was applied in a colour managed workflow using the ICC.2 architecture to render the appearance of the prints on a display. The seven used as samples to the renderings.

Directional Reflectance

Concepts and formulas that are generally useful in atmospheric radiative transfer are gathered here for later use. These include units for light wavelengths and frequencies. Optical elements for instrument description and characterization (solid angle descriptions, étendue, and the diffraction limit) are presented. Lambertian reflectance and emission properties are described, and the bi-directional reflectance distribution function, BRDF, introduced.
