A floodlight is a point light source that can uniformly illuminate in all directions, and its illumination range can be adjusted arbitrarily. In the scene, it usually appears as an icon of a regular octahedron. Floodlights are widely used in rendering production. Standard floodlights are used to illuminate the entire scene, and multiple floodlights can be applied in the scene to produce better effects. The characteristics of floodlights include high brightness, energy saving and environmental protection, strong durability, and high safety.
The specific applications of floodlights include lighting in places such as billboards, highways, railway tunnels, bridges and culverts. In addition, floodlights also include diffuse lights, sky lights, floor lights, etc. These lamps belong to soft light type lamps, with delicate and soft light, forming a complementary relationship with the spotlight series. When used for object lighting, the speed of lighting reduction is much slower than when using spotlights, and some floodlights even look like a light source that does not produce shadows.
