How does ambient occlusion contribute to the realism of a scene?
Understand the Problem
The question is asking about the role of ambient occlusion in enhancing the realism of a 3D scene, specifically how it affects various lighting and shadow effects within that scene.
Answer
Ambient occlusion adds realism by simulating ambient light's soft shadows and depth, enhancing details and object separation.
Ambient occlusion (AO) enhances the realism of a scene by simulating soft shadows and depth resulting from ambient light interacting with objects. This technique accentuates surface details, creates contrast, and helps separate objects visually, making them appear more lifelike.

More Information
Ambient occlusion does not rely on direct light sources and instead calculates areas less exposed to ambient lighting, helping to create realistic transitions between light and shadow.
Tips
A common mistake is overusing ambient occlusion, leading to scenes that look unnaturally dark or have a dirty appearance.
