Physically Based Rendering

Physically Based Rendering (PBR) is a technique in computer graphics that simulates the way light interacts with surfaces in a realistic way. Instead of using simplified or exaggerated shading, PBR models materials based on real-world physical properties like how shiny, rough, or translucent they are. This approach ensures consistent and believable lighting across different scenes and materials, making digital images look more natural. By accurately capturing phenomena like reflections, shadows, and surface textures, PBR helps create visuals that closely resemble real-world objects and environments.
