What best describes Directional Light in Autodesk 3D Studio Max?

• A. Rays in all directions from a single source.
• B. Parallel light rays in a single direction; simulate sunlight; color and orientation adjustable.
• C. Dome above the scene.
• D. Emits light from a volume.

Answer: (B)

Directional light models sunlight: its rays travel in parallel in a single direction, and the light level doesn’t fade with distance. You set where it’s pointing by orienting the light, and you can adjust its color to simulate different times of day. This makes it ideal for outdoor scenes where distant, parallel illumination is desired and shadows are cast consistently across objects. The other concepts don’t fit because a point (omni) light emits in all directions from one point, not parallel rays. A dome light represents an environmental or skylight source over the scene rather than a single directional beam. A volume light emits from within a volume, creating light that fills a space rather than coming from a distant, directional source.
