Physically based rendering (PBR) is an approach in computer graphics that renders graphics with more accurate models of light flow in the real world. Many PBR pipelines aim for photorealistic accuracy by simulating the bidirectional reflectance distribution function and rendering equation mathematically. Photogrammetry helps discover and encode accurate optical properties of materials, which shaders can implement to apply PBR principles. Process PBR is a concept that recognizes everything in the real world as shiny, as Joe Wilson puts it. Unlike previous models, PBR differentiates surfaces between non-reflective and reflective by acknowledging even flat or matte surfaces reflect light. PBR integrates photogrammetry to study and replicate real physical ranges of values for accurate simulation of albedo, gloss, reflectivity, and other properties. It emphasizes microfacets, using additional textures and mathematical models to model small-scale specular highlights and cavities. Surfaces PBR topics dealing with surfaces rely on a simplified bidirectional reflectance distribution function (BRDF) model that approximates optical properties using a handful of intuitive parameters. Common techniques are approximations and simplified models fitting approximate data from more accurate methods or laboratory measurements. *Reflection in computer graphics is used to emulate reflective objects like mirrors and shiny surfaces. Accurate reflections can be accomplished by following a ray from the eye to the mirror, then calculating where it bounces and continuing until no surface is found. Approximate reflections can usually be computed faster using environment mapping. Reflection on a shiny surface like wood or tile adds photorealistic effects to 3D renderings. **Diffuse reflection** Diffuse reflection scatters light from a surface at many angles rather than one angle as in specular reflection. An ideal diffuse reflecting surface exhibits Lambertian reflection, showing equal luminance when viewed from all directions. Many materials exhibit a mixture of specular and diffuse reflection. The visibility of objects is primarily caused by diffuse reflection of light: it forms the image of the object in the observer's eye.
