Photorealistic Visualization of Fluorescence Materials with Dual Surface Scattering

Abstract

We describe a simple method to extract fluorescent characteristics of a surface by combining measurements by a "usual" gonioreflectormeter GSCM-4 and fluorimeter FP-8600. The fluorescent BDF consists of three components: glossy near-specular peak which is not fluorescent and white, highly diffuse “passive” part which is also not fluorescent but colored, and fluorescent part. The latter obviates Kasha’s-Vavilov’s rule (factorization) with good accuracy. The BDFs obtained were used in rendering and shown good visual match with the natural photographs.
