HDR Procedural Skies in realtime

Anonymous Nov 23, 2006 at 15:00


This a screenshot from the under development branch of Sylphis3D. It presents a procedural sky shader, running on an SM2.0 card (ATI 9600).

The sky it rendered by simulating several types of atmospheric scatering in realtime, producing a real, high dynamic range sky.

The sky can be parameterized in many ways. From atmosphere thickness to light wavelengths emmition and absorption by sky particles.

I’m a sucker for skies. Can’t wait to see the HDR effect with it.
It looks really great coming from the top, but something looks a little weird around where the white part meets the yellow, with green on top. Not sure if green is supposed to be visible (assuming it’s an earth-like atmosphere)

Great inspiration for my science fair project :-D
