This video was rendered using daytime (NASA Bluemarble) and nighttime (NASA Blackmarble) textures. The volumetric clouds cast shadows during the day and can block city lights at night.

Prototype implementation using level of detail rendering of NASA blue marble data and NOAA elevation data. The planetary cloud cover is implemented using Perlin and Worley noise iteratively warped using curl noise. The shadows of the volumetric clouds are rendered using deep opacity maps. 1280x720 pixel video with 15 frames per second on AMD Radeon Vega 7 graphics (passmark 2034).
