atmosphera

a real-time earth and sky simulator that can move from a location on the ground to orbital distances. set a date, coordinates and altitude, then simulate the day cycle through a sky driven by nasa spice ephemerides. the earth is rendered with a streaming LOD implementation that use AWS open data image tiles and terrarium height data for a breathtaking view of our planet, either from the surface or deep space.

the renderer runs on vulkan 1.3. a frame graph coordinates the hillaire-style transmittance, multi-scattering and sky-view luts with terrain, celestial bodies and 100k+ indirectly drawn stars, as well as the post-process pipeline that features a histogram based auto-exposure, agx/camera response curves and configurable fft convolution bloom.
