Physically Based Rendering
Physically Based Rendering (PBR) is a computer graphics approach that simulates the interaction of light with materials based on real-world physics principles. It uses mathematical models to calculate how light reflects, refracts, and scatters off surfaces, aiming for photorealism across different lighting conditions. PBR has become the industry standard for realistic rendering in games, visual effects, and architectural visualization.
Developers should learn PBR when creating 3D applications requiring realistic materials and lighting, such as video games, simulations, or product visualizations. It ensures consistency across different environments and lighting setups, reducing the need for manual tweaking. PBR workflows are supported by most modern game engines (like Unity and Unreal Engine) and 3D software, making it essential for real-time and offline rendering pipelines.
