3D Scene Lighting

In 3D modeling and animation, lighting can be simulated by using a virtual light source, which can be positioned and directed in the same way as a real light source. The intensity, color, and falloff of the light can be adjusted to create different lighting effects.

In addition to using different types of virtual light sources, 3D artists and animators can also use techniques such as global illumination, which simulates the way light bounces off surfaces in a scene, and post-processing effects, such as color grading, to further enhance the lighting in a 3D scene.
