Type Alias: VolumetricFogSetting
VolumetricFogSetting =
object
Defined in: src/setting/post/VolumetricFogSetting.ts:5
Settings for VolumetricFogPost (screen-space MVP). See the post class for an explanation of trade-offs vs a froxel grid.
Properties
enable
enable:
boolean
Defined in: src/setting/post/VolumetricFogSetting.ts:7
Whether the post pass runs. Toggled by addPost / detach.
density
density:
number
Defined in: src/setting/post/VolumetricFogSetting.ts:10
Beer-Lambert extinction coefficient per unit distance. 0.0 disables fog absorption. 0.05 is a good baseline.
scatteringIntensity
scatteringIntensity:
number
Defined in: src/setting/post/VolumetricFogSetting.ts:13
Multiplier on accumulated scattering. Punchier values amplify "god rays" near the sun. 1.0 default.
anisotropy
anisotropy:
number
Defined in: src/setting/post/VolumetricFogSetting.ts:17
Henyey-Greenstein phase asymmetry [-0.99, 0.99]. Positive = forward scatter (light shafts visible looking toward sun); negative = backward; 0 = isotropic. 0.6 is canonical.
maxDistance
maxDistance:
number
Defined in: src/setting/post/VolumetricFogSetting.ts:20
Cap the ray-march distance in world units. Past this, transmittance saturates. 100 default.
stepCount
stepCount:
number
Defined in: src/setting/post/VolumetricFogSetting.ts:23
Number of march steps per pixel. 16 (cheap, banded) → 64 (smooth, expensive). 32 default.
ambient
ambient:
object
Defined in: src/setting/post/VolumetricFogSetting.ts:26
Ambient scattering tint added at every step (independent of the directional light). Useful for low-key blue night fogs.
