Chapter 655: FogExp2

Core Idea

This class can be used to define an exponential squared fog, which gives a clear view near the camera and a faster than exponentially densening fog farther from the camera.

Key Concepts

• color : Color: The fog's color.
• density : number: Defines how fast the fog will grow dense.
• isFogExp2 : boolean (readonly): This flag can be used for type testing.
• name : string: The name of the fog.

Code Examples

const scene = new THREE.Scene();
scene.fog = new THREE.FogExp2( 0xcccccc, 0.002 );

• What it demonstrates: Typical usage of FogExp2.
