Lighting Models

Lighting models are mathematical frameworks used in computer graphics to simulate how light interacts with surfaces, determining the color and brightness of pixels in rendered scenes. They calculate illumination based on factors like light sources, material properties, and viewer position to create realistic or stylized visual effects. Common models include Phong, Blinn-Phong, and physically-based rendering (PBR) approaches.

Also known as: Illumination Models, Shading Models, Light Models, Lighting Algorithms, Render Lighting

🧊Why learn Lighting Models?

Developers should learn lighting models when working on 3D graphics, game development, or simulation software to achieve visual realism and artistic control. They are essential for rendering engines in tools like Unity or Unreal Engine, enabling effects such as shadows, reflections, and material shading. Understanding these models helps optimize performance and create immersive user experiences in applications ranging from video games to architectural visualization.
