A renderer that generates highly realistic images of the Earth from outer space.
Rendering is done with Path Tracing in participating media.
- Uses measured data for density and light response (extinction coeficients and scattering functions) of atmospheric gases.
- Rayleigh scatterers: Nitrogen (N2), Oxygen (O2), Carbon Dioxide (CO2)
- Mie scatterers: Water vapour
- Other absorbers: Ozone (O3)
- Uses textures from NASA for ground albedo, water bodies, topology, clouds.
- Uses spectral rendering to get an accurate representation of colours.
- Uses importance sampling in the form of direct light (sun) sampling and phase function pdf.

- Install dependencies of the renderer. (Assuming you have Python)
pip install -r requirements.txt
-
Then download textures from here (google drive) and drag them into the
textures
folder. -
Finally, to run Earth Viewer,
python main.py
- Drag with your right mouse button to rotate the camera.
- Press
W/A/S/D
to move the camera.- Press 'Q' to rotate the camera to Earth's surface
- Press 'E' to reset camera rotation
- Press SPACE to go up
- Press CTRL to go down
- Press
P
to save a screenshot.
