The bidirectional reflectance distribution function (BRDF; $${\displaystyle f_{\text{r}}(\omega _{\text{i}},\,\omega _{\text{r}})}$$ ) is a function of four real variables that defines how light is reflected at an opaque surface. It is employed in the optics of real-world light, in computer graphics algorithms, … See more The Spatially Varying Bidirectional Reflectance Distribution Function (SVBRDF) is a 6-dimensional function, $${\displaystyle f_{\text{r}}(\omega _{\text{i}},\,\omega _{\text{r}},\,\mathbf {x} )}$$, … See more BRDFs can be measured directly from real objects using calibrated cameras and lightsources; however, many phenomenological and analytic models have been proposed including the Lambertian reflectance model frequently assumed in … See more BRDF fabrication refers to the process of implementing a surface based on the measured or synthesized information of a target BRDF. There … See more Physically realistic BRDFs have additional properties, including, • positivity: $${\displaystyle f_{\text{r}}(\omega _{\text{i}},\,\omega _{\text{r}})\geq 0}$$ See more The BRDF is a fundamental radiometric concept, and accordingly is used in computer graphics for photorealistic rendering of synthetic scenes (see the rendering equation), as well as in computer vision for many inverse problems such as object recognition. … See more Traditionally, BRDF measurement devices called gonioreflectometers employ one or more goniometric arms to position a light source and a … See more • Albedo • BSDF • Gonioreflectometer • Opposition spike See more WebWe introduce a Spatially-Varying BRDF model tailored to the multi-scale rendering of scratched materials such as metals, plastics or finished woods. Our approach takes advantage of the regular structure of scratch distributions to achieve high ...
