Answer: Direcional.

## Explanation A **directional light source** (luz direcional) is one that is considered to be at an infinite distance from the scene, producing parallel light rays similar to sunlight. This type of light source: - **Simulates sunlight**: The light rays are parallel, as if coming from a very distant source like the sun - **Has uniform direction**: All light rays travel in the same direction - **No distance attenuation**: Since it's at infinite distance, the intensity doesn't decrease with distance **Why the other options are incorrect**: - **A) Pontual (Point light)**: Emits light in all directions from a specific point in space (like a light bulb) - **B) Ambiente (Ambient light)**: Provides uniform illumination from all directions, not directional - **D) Spot (Spot light)**: Emits light in a cone shape from a specific point (like a flashlight) - **E) Difusa (Diffuse light)**: Refers to scattered, non-directional light, not a specific light source type In computer graphics and 3D rendering, directional lights are commonly used to simulate sunlight because they provide consistent, parallel illumination across the entire scene.
