属性

天空类型

使用的天空模型。

Preetham

Based on the 1999 paper by Preetham et al.

Hosek/Wilkie

Based on the 2012 paper by Hosek and Wilkie.

Nishita

太阳方向

太阳方位矢量。

浑浊度

大气浑浊度。

值设定为2：类似北极的天空
值设定为3：晴空万里
值设定为6：温暖潮湿的天气
值设定为10：雾天

地面反照率

Amount of light reflected from the planet surface back into the atmosphere.

日轮

Enable/Disable sun disc lighting.

太阳尺寸

Angular diameter of the sun disc (in degrees).

太阳强度

Multiplier for sun disc lighting.

太阳高度

Rotation of the sun from the horizon (in degrees).

太阳旋转

Rotation of the sun around the zenith (in degrees).

海拔

The distance from sea level to the location of the camera. For example, if the camera is placed on a beach then a value of 0 should be used. However, if the camera is in the cockpit of a flying airplane then a value of 10 km will be more suitable. Note, this is limited to 60 km because the mathematical model only accounts for the first two layers of the earth’s atmosphere (which ends around 60 km).

空气

Density of air molecules.

0 no air
1 clear day atmosphere
2 highly polluted day

灰尘

Density of dust and water droplets.

0 no dust
1 clear day atmosphere
5 city like atmosphere
10 hazy day

臭氧

Density of ozone molecules; useful to make the sky appear bluer.

0 no ozone
1 clear day atmosphere
2 city like atmosphere

输出
