Class: VolumetricFogPost

Defined in: src/gfx/renderJob/post/VolumetricFogPost.ts:36

Volumetric Fog (MVP) — screen-space per-pixel ray-march. Produces directional light scattering ("god rays" / volumetric shafts) and Beer-Lambert distance attenuation in fog.

Consumed via the post chain: addPost(view, new VolumetricFogPost()).

Setting: engine.setting.render.postProcessing.volumetricFog.

Known MVP limitations:

• Compute pass does NOT sample CSM shadow maps along the march (would need the shadow map binding plumbed; deferred). The phase function still biases scattering toward the sun direction so light-shafts read correctly when looking near the light.
• No temporal denoise — increase stepCount if banding shows.
• Single dominant directional light only; point/spot lights don't contribute scattering yet.

Constructors

Constructor

new VolumetricFogPost(): VolumetricFogPost

Defined in: src/gfx/renderJob/post/VolumetricFogPost.ts:42

Returns

VolumetricFogPost

Overrides

PostBase.constructor

Properties

enable

enable: boolean = true

Defined in: src/gfx/renderJob/post/PostBase.ts:23

Inherited from

PostBase.enable

isFinalPass

isFinalPass: boolean = false

Defined in: src/gfx/renderJob/post/PostBase.ts:27

When true, PostPass iterates this post AFTER every regular post regardless of attach order — used by TonemapPost so the ACES curve always lands on the fully-composited HDR signal.
