Re: [Flightgear-devel] [PATCH] crease for ac3d files and speedup
Hi,
During digging for that adf.ac stuff I have done some minor adjustmens to that
patch.
Things like not storing texture coordinate arrays when there is no texture
attached to that object and such.
The updated patch is attached.
Wolfram, this is the current one :)
Greetings and Thanks

[Flightgear-devel] [PATCH] crease for ac3d files and speedup
Mathias Fröhlich a écrit : Hi, During digging for that adf.ac stuff I have done some minor adjustmens to that patch. Things like not storing texture coordinate arrays when there is no texture attached to that object and such. The updated patch is attached. Wolfram, this is the current one :) The windows binary for this patch is here : ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/fgfs-0.9.6-20041009.zip -Fred ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

[Flightgear-devel] [PATCH] crease for ac3d files and speedup
Hi all,
During the past days I have done some profiling on flightgear. One final
outcome of that work was, that most time is spent in ssg routines (yes, ssg
not OpenGL!!). The problems are the huge amount of small leaf nodes we get
from the ac file loader. That vertex optimization pass makes this a bit
better but there was still room for improovement.
I have now changed the ac3d file loader to first collect all surface elements
of a leaf object and then split them to a minimum number of leaf nodes
according to material and colour properties.
For my local setup (radeon 9100, athlon XP 2400+) this gave me a framerate
speedup up to 40% (16 fps - 26fps, for the c172 rendered in a window to not
hit the ancient radeons fill rate limit). I would guess that the average
speedup is about 25%-30%.
As a /sideeffect/ it was now easy to implement the crease tag for ac3d files.
Ac3d models look now the same as in ac3d.
Attached is a patch to todays plib anoncvs.
Is sombody there with cvs write access to plib? Can somebody apply this patch,
please?
Greetings
Mathias

I've tried using display lists again (which didn't work in the past) and
on my O2 I get a great improvement (up to 30%, but that only means from
6 fps to 9 fps in my case), but on my Linux machine I get a floating
point exception.
Could anyone test it on their Linux machine?

Can anyone isolate where in the code this is breaking ? If so please post the offending SSG calling function with code and stack trace if possible Also are we sure that all variables are initialized in the parsing code might be worth initializing everything of interest with bogus values like (FLOAT_MAX * -1) to make any unitialized value easier to spot. will need to step thru some of the new parsing code and setup code in gdb todo this I would work on this as this is an obvious improvement but I don't have a Linux Box with a Radeon Cheers Norman ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
