Brdf acquisition with basis illumination

WebJan 30, 2024 · In this paper we present a practical adaptive method for acquisition of anisotropic BRDF, based on sparse adaptive measurement of the complete four-dimensional BRDF space by means of one-dimensional slices, which form a sparse four-dimensional structure in the BRDF space, and can be measured by continuous … Web2 D-BRDF Basis Most BRDF models are unfortunately not easily separated into a structured illumination and a reflected light basis, which presents a challenge for deriving the appropriate basis illumination. How-ever, the D-BRDF model is an example of a model where such an illumination basis can constructed for measurements in the back-
