SkyParameters

Remarks

Turbidity is the knob that moves the look most and the one whose name says least. Raising it widens the sun's aureole, desaturates the blue and brings the horizon up — which is haze, and which reads as distance.

Fields and properties (3)

• public Vector3 SunDirection

  Which way the sun's light travels — toward the scene, the same sense Direction has. Normalised on use.

• public float Turbidity

  How much haze there is: the ratio of total to purely molecular optical thickness. 2 is an exceptionally clear day, 3 a clear one, 6 hazy, 10 the sky over a city in summer.

• public float GroundAlbedo

  What the ground below the horizon reflects, 0 to 1. Not part of the daylight model — it is what the lower hemisphere of a baked cube is filled with, and it is the difference between a scene with a bounce off the floor and one lit from above only.

Methods (1)

• public SkyParameters(Vector3 SunDirection, float Turbidity = 3, float GroundAlbedo = 0.15)

  The atmosphere, as the three numbers that decide what a daylight sky looks like.
