What is Area Light?
Area lights are a type of light that is used to illuminate a specific area in a scene, as opposed to a point or spot light which shines in a single direction. Area lights can be used to create realistic-looking lighting effects, and are often used in scenes that contain objects with complex shapes.
In 3D visualization, area lights are often used to create realistic lighting effects for scenes that contain objects with complex shapes. By using area lights, you can create shadows and highlights that look more realistic than if you were to use a point or spot light. Additionally, area lights are often used to create ambient lighting effects in a scene. Ambient lighting is the type of lighting that affects everything in a scene equally, and is used to create a sense of realism.
