Physically based rendering (PBR) is a rendering technique that aims to simulate the interaction of light with materials in a realistic manner, resulting in images that accurately represent the physical properties of surfaces. This approach leverages real-world measurements and physical laws to achieve photorealism, making it essential for creating immersive and convincing virtual environments. By using models that account for factors like light reflection, refraction, and scattering, PBR enhances the visual quality of rendered images and allows artists to create more believable scenes.
congrats on reading the definition of physically based rendering. now let's actually learn it.
