Glint rendering, useful for simulating the appearance of glittery materials, brushed metal or scratched plastic, is a theoretical and technical challenge in computer graphics. It involves the use of spatially varying patch bidirectional reflectance distribution functions (P-BRDFs) with high frequencies. In this thesis we propose two new P-BRDFs based on specular normal maps. Unlike the previous method [YHMR16], our first BRDF prevents any creation of energy through footprint-dependent normalisation. This normalisation is possible thanks to a new representation of the normal map based on a mixture of non-centered and non-axis aligned Beckmann NDFs. The second method improves the first one and prevents, for the first time, any creation and lo...
