Atmospheric fog, in the context of visual rendering, is a technique that approximates light scattering through a planetary atmosphere to create a more realistic outdoor environment. The main objective is to simulate how light interacts with the atmosphere, enhancing the visual depth and realism of scenes.
Key Aspects of Atmospheric Fog:
- Light Scattering Simulation: Atmospheric fog emulates how light particles interact with the atmosphere.
- Realistic Outdoor Levels: Adding atmospheric fog can give outdoor levels a more realistic look.
- Sun Disc Effect: The directional light (often representing the sun) will have a visible disc effect in the sky.
In essence, atmospheric fog enhances realism by mimicking atmospheric light interactions.
