[Flightgear-devel] Repeatable random seeds
Hello everybody,
lately I've been working on a multiscreen setup driven by multiple host
machines. In order to get the same random scenery objects, all machines
need to use the same random seed. Up to now, the random seed is taken
from system time, which leads to inconsistencies.
The attached patches add a command line option --random-seed=,
which allows to explicitly specify a (positive) seed, or -1 (the default
when the option is not given) to seed from system time, or -2 to seed
from system time in 10 minutes intervals.
This is however only a first step, there are remaining inconsistencies,
most prominently 3D clouds differ, even between two runs on the same
machine. I suspect this is because there is only one instance of the
random number generator, which may be accessed in non-deterministic
order from different threads. The solution is probably to make a random
number stream class, of which each relevant subsystem/class/whatever
keeps its own static instance. I'll be looking further into this, but
maybe someone has some experience on this to share?
Best regards,
Andreas

Is this broken.. again? Sigh. I've been pushing this behavior various times and scenery objects should always be positioned at the same location over and over again.

I would argue that Writer, Poet, Engineer _shouldn't_ be bothered by the final look of their design.

Outside of the updates that Martin and I make, I think we get a couple every year. >(We have the GIT for the design - but descriptions for > the users in real time updates?)

As it currently stands, The Manual is targeted at the following people from your list: - A university-Prof studding the possibilities of FlightGear - real pilots that want to train - grown ups - or kids that want to play (and which we maybe able to convince to start simulating in FlightGear instead of playing killing-games) The other two (FAA, FG engineers) require a completely different, much more detailed set of documentation. Frankly I don't think we should be looking to address that while we struggle to address the above users. > Very simply said: Look at the opening question of this thread, and tell > me what you would answerer!

We've been tossing the idea around in the forum that Local Weather stops using the rand() function from Nasal and uses its own internal random number generator. In this way, it could be initialized in a well-defined state on different machines, the sequence could not be messed up by other Nasal scripts running and you'd generate a predictable configuration.

OK. We've got something similar already in the C code for exactly this purpose. Might be more efficient to simply expose that over Nasal, but I'm not sure how easy that would actually be. -Stuart -- BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA Learn about the latest advances in developing for the BlackBerry® mobile platform with sessions, labs & more.

To clarify things up a bit, not all is broken: - Houses etc. are the same - Trees are at the same location and same size, but sometimes have different textures. Looks like this is called by a rand() call in TreeBin.cxx:256, which is probably there because sg_random doesn't have an integer rand function. - both 2D and 3D clouds differ, and as far as I can tell, both in position and texture.

Pretty trivial, for a function such as sg_random, unless I'm missing something really subtle. Basically add a f_random wrapper in NasalSys.cxx, add an entry to the static table at the bottom of the file, and you should be done. Oh, except you need to pick a name that doesn't clash with any internal Nasal rand/random.

There is a small subtilty. I think we need to use the (IIRC) mt_rand() function we're using to ensure a repeatable number for the scenery etc. That uses a structure that is seeded and which controls the sequence of random numbesr I think the Nasal layer would need to pass that structure (or a reference to it) across the interface. Probably not too difficult I agree. -Stuart -- BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA Learn about the latest advances in developing for the BlackBerry® mobile platform with sessions, labs & more.

There is, one of the FGPositioned spatial queries, which could be exposed via
Nasal. However, I already exposed these via an alternate method - I didn't want
to add lots of Nasal proxies for each item we have. You can issue a search via
a regular flightgear command, and the resulting navaid(s) can be stored into an
arbitrary property tree location.
The command is called 'find-nearest', it takes a maximum search radius in NM, a
search position, and list of types to search on (NDB, ILS, VOR, or anything
else in the positioned DB).
Eg, from Nasal:
fgcommand("find-nearest", props.Node.new({type: "vor", max-results:10,
results:"/some/node/path"}));
Will load the ten closest VORs to the current aircraft lat/lon below
/some/node/path
(or as many as possible within the default search radius, 400 nm)

Re: [Flightgear-devel] ZKV1000 buildmaps.pl on Windows 7
Hi Alan,
I'm the author of buildmap.pl script. Hope not being too late.
I've no windows box here, but I had a WinXP on a virtual machine, which
I've used to test the script (not have it anymore though). AFAIR it
worked quite well on the VM but it was a long time ago and I don't
remeber if my tests included the directories creation (mkdir) :/. The
only problem I remember was to find matching imagemagick and perl
versions for my XP platform.
I've just checked here on my linux box (perl 5.12 perlmagick 8:6.6.9.7)
with sceneries from my computer, and images built from atlas/cvs on
dated 2010-09-28 (ouch... old), everything seems to be OK, correct
images have been created.
Sure the script does not embed any documentation at all. I know this is
a pity, indeed the script do nothing very complicated, and it was not
dedicated to be published before being cleaned and commented. No

Hi Alan I see now also some differences between OSM and "our" apt.dat and the title of this post is probably wrong (as many other details sometimes coming out here from the university of half-knowledge). Some of the airports and runways fit exactly on all the maps. Maybe "edited" airports ? I dont know, it is very difficult to verify for me, maybe I am on some bad and exotic examples only. (I was thinking about what happens with "wrong" runway coords from apt.dat, i.e. when this data is processed via shapes with recent landcover and height data for FlightGear scenery, coming from other resources. But I confess this gives me to much smoke over my head, also without taking slopes and hills into account). > > Point positions of aeronautical navaids and airfields have mostly been well > surveyed and their positions should therefore be accurate. > Yes, I think (or hope) so ;-) Also here, I only see differences between apt.dat and other geodata. We use X-Plane data, OSM uses another aeronautical database with more than 4 airports recently in public domain (ourairports.com). I dont know if this is based on the older but unfortunately disappeared DAFIF resources too, but anyway it looks like it is also an interesting collection and has a "living" updater community. I just discovered this one, I will do some private examples with this data. And be quiet for the rest of the year, or at least for some days.

Re: [Flightgear-devel] ZKV1000 buildmaps.pl on Windows 7
Sébastien
Thanks for the quick response. I have done a git "pull" and am pleased to
report that the glob and mkdir errors have now disappeared. .-)
However I am still left with the three vertical bands as shown in my
previous post.
(http://v-twin.dynip.sapo.pt/alan/VickersAircaft/TSR2/maps/e000n51.png) :-(
My atlas maps were built as 1024x1024 images if that is any help.
On ZKV1000 and Atlas tiles, e.g. the e000n51.png as above, do you know what
are the pixel coordinates of the reference point ( i.e. e000n51) and what
are the tile coverages?

Hi Alan,
I'm the author of buildmap.pl script. Hope not being too late.
I've no windows box here, but I had a WinXP on a virtual machine, which
I've used to test the script (not have it anymore though). AFAIR it
worked quite well on the VM but it was a long time ago and I don't
remeber if my tests included the directories creation (mkdir) :/. The
only problem I remember was to find matching imagemagick and perl
versions for my XP platform.
I've just checked here on my linux box (perl 5.12 perlmagick 8:6.6.9.7)
with sceneries from my computer, and images built from atlas/cvs on
dated 2010-09-28 (ouch... old), everything seems to be OK, correct
images have been created.
Sure the script does not embed any documentation at all. I know this is
a pity, indeed the script do nothing very complicated, and it was not
dedicated to be published before being cleaned and commented. No
interface neither help is provided yet...
BTW have you checked the last available version:
https://gitorious.org/zakharov/zkv1000/blobs/master/Systems/buildmaps.pl
? (I've just pushed last changes from 3 monthes ago before writing this
mail)

Our posts have overlapped. These are now OK, but I still have the vertical
bands.
