Measuring an appearance property of a surface using a spatially under-sampled bidirectional reflectance distribution function

An apparatus for measuring a spatially under-sampled Bidirectional Reflectance Distribution Function (BRDF) of a surface. The apparatus may comprise a first light source directed to illuminate the surface from a first illumination direction, and a plurality of sensors positioned to receive light ref...
