Which light models daylight and is typically represented as a dome above the scene?

• A. Dome above the scene.
• B. Only for spotlights.
• C. Emits from volume.
• D. Parallel sunlight.

Answer: (A)

A dome light is used to model daylight by enclosing the scene in a hemispherical light source that sits above and around the scene. This setup allows light to come from all directions, mimicking the diffuse sky and sun, which produces natural-looking daylight with soft shadows and even illumination. It’s the standard way to simulate environmental lighting in a daytime scene because it captures the broad, ambient skylight that a single directional sun or a handful of spotlights cannot. In contrast, a light that’s only for spotlights isn’t providing the surrounding background light; emitting from volume describes light that originates inside a volume rather than from a surrounding surface; and parallel sunlight refers to a directional light that mimics a distant sun with parallel rays, which doesn’t envelop the scene like a dome light does.
