Earth from Space

Because I'm performing a brute force atmospheric simulation, I'm able to render the atmosphere from any point of view. After a few tweaks, I'm now able to render images from outside the atmosphere. Here are a few images that show what the Earth looks like from space. The planet's surface is currently an 18% gray Lambertian diffuse reflector.

The planet as seen from 200 km up.

Same view as above, but with no atmosphere.

A different view. Also 200 km up. Sun right below the horizon.


  1. Hey Peter,

    I'm the lead of appleseed, an open source physically-based renderer targeted at production.

    I've been following both of your blogs for a while now. Excellent work.


    1. Hey Franz,

      Thanks for your comment! I'm happy that you like my blogs.

      I've come across appleseed before. It looks very nice!
