A work in progress. More here: poniesandlight.co.uk/experiments/world.html

The atmosphere calculations are based on Sean O'Neill's classic, with some fragment-space tweaks, the Parallax shader for the clouds is stylists' own, as are the bump maps, rendered from NASA depth data (poniesandlight.co.uk/notes/creating_normal_maps_from_nasa_depth_data/).

Uses modern GLSL / OpenGL with the new programmable GL renderer in openFrameworks 0.8.

Original Nasa Data: Reto Stöckli, NASA Earth Observatory (visibleearth.nasa.gov/view.php?id=73934)
Music: "Steiner im Flug" by Pantha du Prince (panthaduprince.com/)

Runs @ 60 interactive fps in HD (1920x800) on a AMD Radeon HD 6750M GPU.

Made with openFrameworks.
