However, as every PBR system is based on the same principal idea (render stuff as accurately as possible) many concepts will transfer easily from project to project or engine to engine. PBR is more of a concept than a strict set of rules, and as such, the exact implementations of PBR systems tend to vary. Physically based rendering (PBR) refers to the concept of using realistic shading/lighting models along with measured surface values to accurately represent real-world materials. Fast becoming a standard in the games industry due to increased computing power and the universal need for art content standardization, physically based rendering aims to redefine how we create and render art.
