Which light model is used to simulate daylight and is typically a dome above the scene?

• A. Directional Light
• B. Skylight
• C. Area Light
• D. Omni Light

Answer: (B)

Daylight is best modeled with a skylight, because it represents the broad, diffuse illumination coming from the sky. Placed above the scene, often as a dome, it captures ambient sky light and washes across surfaces evenly, producing natural, soft shadows. This differs from a directional light, which mimics a single distant sun with sharp, directional rays; an area light, which emits from a defined surface; and an omni light, which acts as a point source emitting in all directions. So the skylight is the standard choice for daylight coming from overhead.
