ambientIntensity
AmbientIntensity is a scalar factor used in computer graphics to control the strength of the ambient lighting component in a lighting model. Ambient lighting represents indirect, scattered light that has been reflected many times in a scene, and it helps prevent surfaces from appearing completely dark in areas not directly lit by a light source. The ambientIntensity parameter scales this contribution to suit a particular scene or artist’s intent.
In typical shading equations, the ambient term may be written as a product of the material’s ambient
Common ranges for ambientIntensity are 0.0 to 1.0 in simple lighting setups, where 1.0 provides full ambient
Modern rendering often replaces a single ambient term with more physically based approaches, such as image-based
