When creating Earthviewer, I used a bunch of free libraries and assets. Here are the most important ones:



  • Natural Earth III: Earth image data, going from texture maps to elevation maps. I used a night texture, a cloud map and the land/water mask.
  • NASA Visible Earth – The Blue Marble: This is where the day texture is from and I also used one of their Bathymetry maps.
  • Ponies & Light Normal Map: The personal blog of @tgfrerer, he wrote an article about extracting normal maps from elevation data. I used his results in my project.
  • Milky Way Skybox Textures: Originally made for Kerbal Space Program using Space Engine. Unfortunately I do not know the author because of his reddit and mediafire account being deleted.

I also want to appreciate some tutorials which helped me alot:
