Anti Aliasing

[iperich]

Hi, I'm using Oolite 1.82 64 bits in Windows 8, and I would like to set anti aliasing, I read that Oolite supports anti aliasing and you can set it in the .GNUstepDefaults file in the oolite.app/GNUstep/Defaults directory with the line

"anti-aliasing"=1;

well, I did it but I see no difference at all, I tried "anti-aliasing"=YES too and no results.

It is possible to have anti-aliasing? Am I doing something wrong or missed something?

Thanks in advice.

I am not sure I have seen any difference with or without the defaults anti-aliasing switch either, but to be honest I've never paid too close attention to it. It may be possible that driver antialiasing settings are overriding whatever it is that SDL is trying to do?

[Cody]

I have my nVidia CP set to override application AA settings (for Oolite) - but I wasn't aware that Oolite had its own AA setting.

[iperich]

In the driver config I have anti-aliasing "configured by application", the other option is "disabled"...

What video card do you have? Could you please post the beginning of a log, where the list of OpenGL version and extensions are provided?

[iperich]

Oh, I have an Intel HD Graphics 4000.

in the config file I have "anti-aliasing"=1;

[another_commander]

Thanks for posting the details. I think that the problem is that you are missing the OpenGL extension WGL_ARB_pixel_format. Looking at what SDL on Windows does, it seems that it requires this extension in order to enable multisampling AA. If the extension does not exist, then the calls to set AA will fail silently.

[cim]

I added it a while back because it was easy to do, but I've no idea how widely supported it is, which is why it's hidden as a largely undocumented config setting.

Works for me on Linux+Nvidia is all I can really say for it.

... which is why it's hidden as a largely undocumented config setting.

Are there any other hidden Oolite gfx settings? I can never find that list of hidden stuff.

[another_commander]

You mean this? http://wiki.alioth.net/index.php/Hidden ... _in_Oolite

[Cody]

That's the one - now bookmarked, thanks.

there's something I can do, then?

[Cody]

Do you have the latest drivers for your gfx card? If not, an update might help.

did it already.....

[Cody]

Oh well... I guess you're stuck with what your gfx card itself can deliver.
