FGx 2.8.0rc3 for OSX with mountain lion support

Postby gral » Sat Jul 28, 2012 10:49 am

Hi all

This is the release candidate 3 for FGx with mountain lion ( OSX 10.8 ) support now. It will still work for 10.5/6/7 of course. When you want to test this candidate please download here http://downloads.fgx.ch/OSX/FGx-2.8.0rc3.zip (~750 mb). Unzip the file and move "FGx" to your Applications folder. Please overwrite, remove and/or rename older FGx versions.

Hi -gral, thanks for sharing!

Could you tell me how I can enable antialias? I'v tried with this code:

Code: Select all
--prop:/sim/rendering/multi-sample-buffers=true
--prop:/sim/rendering/multi-samples=8


but it doesn't work! :/

If you are using Rembrandt, MSAA is not supported. You have to rely on your driver for anti aliasing. Otherwise it should work although the number of samples (8) may not fit well with your GPU memory. You can try 2 or 4.

Thanks fredb for you answer,

I'm not using Rembrandt...I think it's not possible to adjust graphics driver settings on MacBook Pro, is it?

I tried 4 and 2, but it still doesn't work.

Are you sure your GPU support multi sample anti aliasing ?

Anti-aliasing doesn't work on my Mac either. Maybe someone could add an easy anti-aliasing switch in FGx?

Other than that, this rc works almost fine on my Mac. However, FlightGear doesn't exit properly, but crashes "on demand" instead (I already reported this issue in the bug tracker). Does this happen to anyone else?

On FG 2.6 anti-aliasing was enabled ( level 8 ) and it worked!

Tat applied a lot of useful and glorious patches to macflightgear 2.6.0 and OSG source. Currently the anti-aliasing is not supported out of the box with this FGx RC's here because this patches are not applied yet (but I'm working now on this issues). It's always good to see what features are currently missing, thanks for your reports !

Cheers, gral

Ouchhhhh ! What a horror I found here:

traits->sampleBuffers = fgGetInt("/sim/rendering/multi-sample-buffers", traits->sampleBuffers);

This means: You have to set
--prop:/sim/rendering/multi-sample-buffers=1

and anti-aliasing is working fine, at least here.

Thanks, gral

EDIT:
This all means now when you want to enable anti-aliasing with FGx for FlightGear you have to go to the "Expert options" tab, activate "Additional Command Arguments" and paste this props:

Code: Select all
--prop:/sim/rendering/multi-sample-buffers=1
--prop:/sim/rendering/multi-samples=4


Choose a multi-samples count between 1 and 8, >8 not recommended :wink:

btw. adding a "Rendering" tab to FGx is a pending task here, then you will not have to add such arguments manually anymore.
