THREE.JS / TSL HEIGHT FOG

Air gathers near the ground.

A bounded implementation of the official exponential height-fog graph: 100 instanced columns sit below a tunable fog plane while the native lane uses exponentialHeightFogFactor.

The native route assigns scene.fogNode = fog(color, exponentialHeightFogFactor(density, height)). WebGL2 is an explicitly labeled FogExp2 reference. Official Inspector presentation, exact camera/page/pixels, and whole-example fidelity remain separate. Official example
