What is a ambeant acclusion?

## Answers

### Answer by Hitesh Vohra

- The term **'ambient occlusion'** refers to how bright light shines on various surfaces. AO is depending on the surface's surroundings.
- The calculation is done by projecting rays from the surface in all directions.
- The brightness of the surface is boosted by focussing the background light.
- On the visible hemisphere, points with little geometry will seem light.
- Ambient occlusion is a shading and rendering technique used in 3D [**computer**](https://answers.mindstick.com/qa/97060/why-do-we-want-smarter-machines-or-computers-or-robots) graphics, modelling, and animation to calculate how exposed each point in a scene is to ambient lighting. Ambient occlusion can be thought of as a determined accessibility value for each surface point.
