Physicalbased
Physicalbased is a term used to describe physically based rendering and shading workflows in computer graphics. These approaches aim to reproduce plausible light-material interactions based on real-world physics, producing materials that look consistent under varying lighting conditions. Key principles include energy conservation, physically plausible reflectance, and parameterized material properties that map to real surface characteristics.
Core concepts include the microfacet BRDF, typically modeled with distributions such as GGX, which describe how
Implementation context: PBR is widely adopted in modern game engines (Unity, Unreal, Godot) and content-creation tools
Limitations and scope: While PBR improves realism and consistency, it is a simplified model of light transport.
