FogRenderer

Remarks

A post-process rather than a per-material term, and that is what makes it affordable: fog depends on the distance from the camera to whatever was drawn, which the depth buffer already holds for every pixel of the frame. Adding it in every material's shader would mean every material carrying the fog's parameters and evaluating it whether it is on or not.

Fields and properties (12)

• public required string Source

  The colour it fogs.

• public required string Depth

  The depth it reads distance from.

• public int Mode

  Which falloff curve is used.

• public bool HeightFalloff

  Whether fog thins with altitude, as an atmosphere does.

• public bool SunScattering

  Whether looking toward the sun brightens the fog.

• public RenderView? View

  Clip space back to world, for reconstructing where a pixel was.

• public Matrix4x4 InverseViewProjection

  Clip back to world, when no View supplies it.

• public Vector3 CameraPosition

  Where the camera is, which the distance is measured from.

• public Vector3 Colour

  The fog's colour.

• public float Density

  How quickly it accumulates with distance.

• public float Start

  Where it begins, for the linear mode.

• public float End

  Where it is fully opaque, for the linear mode.

Methods (3)

• public FogRenderer()
