The video features a 3D animation of a sphere on a platform with a checkered background. The sphere is illuminated by multiple light sources, creating a pattern of green lines that represent the light rays. The animation demonstrates the difference between "reflections" and "global illumination" in terms of lighting effects. The sphere is shown from different angles, and the light rays are animated to show the direction and intensity of the light. The video also includes text that explains the difference between the two lighting techniques, and the phrase "more FPS!" appears, indicating a performance improvement with global illumination.
