Which statement describes Omni Light?

Which statement describes Omni Light?

• A. Emits light from a volume rather than a point source.
• B. Rays in all directions from a single source.
• C. Parallel light rays in a single direction; simulate sunlight.
• D. Models daylight as a dome above the scene.

Answer: (B)

Omni light is a point light: it emits light in all directions from a single point in space. This makes it behave like a bare bulb, radiating light uniformly outward in every direction, which is why the description of rays in all directions from a single source fits. It isn’t emitting from a volume (that would be an area or volumetric light), nor sending parallel rays in one direction (that would be a directional or sun light), nor modeling daylight with a dome above the scene (that’s a dome/skylight setup). In practice, you place an Omni at the light’s position, and its intensity and color determine how bright and warm or cool the light feels, with falloff depending on distance.
