Ambient light plays a crucial role in the visual presentation of objects within a scene. Unlike direct light sources, which cast distinct shadows, ambient light provides overall illumination, influencing the perception of colors and shapes. It is the encompassing light that fills the environment, softening shadows and contributing to the overall mood of a visual composition.
In 3D rendering, ambient light is often simulated to enhance scenes where direct light sources may not fully illuminate all surfaces. This technique ensures that objects are not left entirely in darkness, creating a more natural and visually appealing representation. Artists and designers carefully balance ambient light with other lighting elements to achieve the desired atmosphere in a virtual environment.
