Thanks for investigating that - I've not had time to work on or use FG for 
quite a while now, but I like to keep some idea of what's going on.

I've no idea at all why I didn't add 0.0 right to the bottom of that column but

Re: [Flightgear-devel] Local weather: Clouds redrawn

2010-11-10 Thread thorsten . i . renk
 Thorsten asked me to switch off xxx-loop-flags in /local-weather/ to
 rule out Nasal.

 Set to zero:

 buffer-loop-flag = '0' (double)
 convective-loop-flag = '0' (double)
 dynamics-loop-flag = '0' (double)
 effect-loop-flag = '0' (double)
 housekeeping-loop-flag = '0' (double)
 interpolation-loop-flag = '0' (double)
 lift-loop-flag = '0' (double)
 tile-loop-flag = '0' (double)
 timing-loop-flag = '0' (double)
 wave-loop-flag = '0' (double)


To make that point very clearly: These loop flags determine if particular
Nasal code of local weather runs and does administrative tasks. There is
within local weather a subsystem which does similar things to what is seen
in the video, asymmetric buffering, i.e. it removes clouds not currently
in the visual field and some distance away from the scenery and re-inserts
them if the view angle changes. My initial suspicion was that this
subsystem is running wild - but setting the flags to zero and thus ending
the Nasal loops (in particular buffer and housekeeping) would have
'frozen' the cloud configuration, i.e. it should have left clouds in an
angular wedge visible and clouds everywhere else invisible with no
loading/removing going on (I have checked that on my system that is indeed
what happens).

So since the effect persists even in the absence of any running
weather-related Nasal code, I deduced it must be something else.

Also, I am unable to reproduce the problem on either today's GIT or my old
2.0.0 binary. Maybe someone else has a bright idea...

* Thorsten

 Hi All,
 
 I have been in an exchange of messages with Thorsten 
 (http://www.flightgear.org/forums/viewtopic.php?f=5t=7358p=101746#p101746 
 http://www.flightgear.org/forums/viewtopic.php?f=5t=7358p=101746#p101746) 
 about a problem that I have with the local weather in GIT versions
 (all GIT versions lately in fact).
 
 Clouds are drawn and I can wait for that initially. But when I change 
 the angle of view, clouds are drawn for the new angle of view. When I 
 'turn my head'back to the previous angle, the clouds that were
 already drawn are gone and get redrawn. The same clouds in the same
 place.
 
 In this video, you can see for yourself what I mean:
 http://www.easy-share.com/1912919971/Clouds03.mpg
 
 Needless to say this is bad for realism.
 
 My FPS is not a problem. The effect occurs when the frame rate is
 above 40 fps.

..test ideas; cap your FG at 40fps, or back off a wee bit 
on your X framerate.  X and FG window sizes?

 My machine is a 4 core (8 threads) 12GB ram machine running 64b Linux 
 and an nVidea9800 graphics card. FGFS is run in mulithreading mode. I
 am flying as I type this. No processor is 100% busy and memory
 consumption is only 2.2GB (of which 1GB for fgfs) in total. I have 59
 fps at this moment.

..it _could_ be your video card is the bottleneck here, I had 
a similar problem (angular white texture holes) that I cured
easing my X framerate down from 59Hz to 58.8Hz.

  so here is not a lot we can do. Caveat emptor. 

 It is an affiliate scheme, which is very close to a pyramid scheme.

..if it adds _any_ new required condition to the conditions 
set under the GPL, _that_ new condition is a violation of the

 It is indeed annoying to see people trying to make money out of our
 work.

..and annoyingly irrelevant too. ;oD

 However, they are offering some added value by selling FG on DVD,

 and we can take some satisfaction from the thought that they are
 perhaps spreading FG wider than we could by our own efforts.

..I disagree, until a lawyer is hired by FG or a copyright

FlightProSim reviews, and their advertisers, etc, and ask 
them to explain Why In The World are they endorsing and 
promoting software piracy.  And _loudly_. ;o)

[Flightgear-devel] heads-up: startup.nas for automatic runway selection is obsolete

2010-11-10 Thread Torsten Dreyer
Hi,

I just commited a hack to make startup.nas obsolete and removed it from 
FGDATA/Nasal. The sole purpose of startup.nas was to assign a runway uppon 
startup of flightgear based on wind-direction received from realwx/metar.
Unfortunately, this nasal script called the command presets-commit which 
caused some headache. 
Also, the AI-traffic used a separate logic to assign the active runway to it's 
aircraft which lead to opposite traffic on the runway under certain 
circumstances. 
Now the runway selection takes place in the idle-loop during the 
initialization sequence of fg and the same code is used as for AI traffic.

Please report any bugs that show up due to this change.
(cool - it works great is welcome, too!)

Hi Torsten,

The new mechanism appears to override the --parkpos=foo commandline

I wonder why this has worked before, parkpos was not checked by startup.nas.
Anyway - it should be fixed now.

This amazing software package is Yours Risk Free for only $47.00

Are they not more selling a software package rather than charging a fee for 
the physical act of transferring a copy, which along with offering 
warranty protection for a fee, is all that would seem to be specifically 
allowed in terms of commercial activity relating to FlightGear according to 
the relevant GPL?

I won't make any judgement, but I would advise anyone interested to take a 
look at their main web page and draw their own conclusions.

They also state that FPS is copyrighted and protected under the United 
States and other World Wide Copyright Laws. Can someone claim their own 
copyright in this way over a product based substantially or wholly on a GPL 
source? You tell me...

? My question is, _do_ they offer the source as required under
 the GPL?

Yes, they offer the full source code. Does this offer meet the full 
requirements of how it is to be delivered? I've no idea, but I do recall 
seeing a particular clause which I thought may not have been met. I don't 
have time right now to go back and look again, but I will if people here 
think there is any mileage in following any of this up.

They are not claiming a copyright - they are claiming that  FPS is
copyrighted and protected under the United States and other World Wide
Copyright Laws

Which is an absolutely *true* statement.

It is a true statement intended to deceive and mis-lead  - but
none-the-less, completely true.

I think they just point at flightgear when asked for the source - which
probably does *not* fulfill the letter of the GPL.

Re: [Flightgear-devel] Local weather: Clouds redrawn

2010-11-10 Thread fierst42
I limited the frame rate to 30, used a smaller window. No difference.
However, I noticed that with fewer clouds the effect disappeared. There 
seems to be a relation with cloud density.

Another thing I noticed:
While I am changing the viewing angle, the log window show errors.
First a lot of Warning: TangentSpaceGenerator: unknown primitive mode 9
followed by  several lines of Unknown Chunk: ***UNKNOWN*** (0xA08A)

I assume this has something to do with the scenery. Could it be related?

Ah. The warnings and errors in the log window are related to local 
weather. They do not appear until I use local weather.
