这个实际操作下来确实表现会比较平,可以小改一下,把均匀的那个相位函数也改成schlick的,然后给g一个负值,制造后向散射。 相位函数中的/theta是平行光方向和相机方向的夹角,这里平行光方向是从SkyAtmosphereLightDirection这个节点取到的。 积分 constfloatboost=1.0f;float3S=SunLightIlluminance*phase*sigmaS*boost;floa...
添加太阳:使用天空大气需要在场景里放置主光源,这个主光源将会是太阳的方向,需要在 Directional Light 的 Light 扩展属性里勾选 Atmosphere/Fog Sun Light 让他起效,天空的颜色是由太阳光和大气属性两个因素一起决定的。 日月同辉:场景里是可以放置两个主定向光源的,通过 Light 扩展属性里的 Atmosphere Sun Light In...

Live music is often linked to elaborate light shows, particularly at large outdoor music festivals. However, artificial light at night is one form of environmental pollution, light pollution, and because outdoor festivals emit a substantial amount of artificial light into the environment, they are ...
There are two kinds of light pollution: skyglow and glare. Skyglow comes down from the sky itself. Artificial skyglow is mostly caused by lights fairly distant from the observer, often ones that are completely invisible from the observer's location. The light goes up into the atmosphere and...
