Accurate Atmospheric Scattering

Post by 1337 » Wed Mar 02, 2011 1:40 am

While showing Orxonox to a game developer I met here in Pittsburgh, we also discussed rendering planets. And he knew about an interesting article showing how to create very good looking athmospheric Scattering:

There is also a YouTube video showing the results:

Did you do something similar to show the athmosphere of your own planet?

Looks really nice ... Didn't know that Blender has a game engine... Is it used to create pre-rendered scenes or as a replacement for e.g. ogre ?


Do you mean in the old Orxonox (V1) or in the Planet implementation of the current Orxonox (V2) ?

I meant the Planet in v2. I just remembered that there has been a discussion about the athmosphere.

the Planet class in orxonox uses a billboard for the atmosphere... apart from that I don't think we have anything close to that. but there are some ogre demos related to planets, space, clouds, etc

Yes, Blender has a game engine. It has the advantage that you can skip the conversion process with all its complications and directly use the models you just made in your game.
