I'll post some pics soon. Promise.
I've decided to use the current Fisheye shader even with the aliasing issues and the minor glitches (Small and Large Magellanic cloud flickering).
I've done several tests. With the Fisheye shader and Without it (FOV 45 to 120) and in one of these I recorded videos and then in After Effects, I've applied a Fulldome plugin by Navegar Foundation (paid version).
To be honest, I didn't see any major difference between using the realtime fisheye shader provided by spaceEngine versus the Post effect Fulldome plugin in After Effects. They both had similar results, despite the mentioned glitches and FOV's. So I'll capture a few more videos and test it again on a dome.
This effort is to see if we (space engine community) can adopt SpaceEngine as an alternative tool to FullDome environments.
Anyway, did you tryied to change the render settings of your GPU? You can set AA there if I'm not wrong.
Yes, I have two computers here one with a 7900 Radeon and other with Nvidia 740m. I've forced to apply AntiAliasing, MultiSampling, Triple Buffer(OpenGl) and every other option available to improve quality but when I change the SpaceEngine to Fisheye, it just ignores all these configurations :/
