Re: [Flightgear-devel] Simple atmospheric scattering shader for skydome
Hi. Nice to see my shader brought up some discussion :) First, Vivian, I tried to see your screenshots, but the link wasn't working (server down or something?) so I cannot comment them right now. And I didn't mean the bug with sun reflection on the water being misplaced from the real shader, but sometimes it seems like the sunset effect on the (non shader) skydome is someting like 90 degrees to the left. I'm not sure if it always was like that or did I change something or am I just seeing things. It looks like the brightest spot of the horizon is not where the sun is, but to the left. If someone can confirm (with old version my version if possible), would be much appreciated. Second, Erik, I tried not to change the old behaviour but I needed to move some code around to get better precision in the skydom model. I hope everything works like it did with the non shader version, I didn't quite understand all the equations but the code should not change those. Only behaviour that I did change is the clear color in FG from fog color to black. I don't see anything changing near the ground, but the effect near space is better :) Other topics, mie and rayleigh coefficients are exposed, but maybe I shuold expose the wavelength dependency too, because that is what affects the sky color the most. The idea is that some code in FG/SG would write the proper coefficients depending on weather conditions to make different looking skies. I also uploaded the python code I used for evaluating the shader and calculating the scale coefficients etc. It is here: http://users.tkk.fi/~lapelto2/fgfs/scatter/scatter.py I can also write a wiki article on the subject should it be necessary. In the future, I'd like to see this shader as a post processing effect applied over all rendered objects so we would get a consistent look and feel everywhere. And also, I didn't think about getting this to the next release, it's too late for that. But maybe to the one after that, so we have time to test things first.

Hi Arnt, http://geoffair.org/tmp/makefg ..idea for makefg-1.3.0: WEUSESYSTEMPLIB=1, WEUSESYSTEMOSG=1 Already thought of, and done ;=)) For all the recent versions there are options - PLIBPATH=path OSGPATH=path Which should do what you ask, but I have NEVER installed PLIB nor OSG into a 'standard' system path, so have never tried these options in that case, but they should work... That is why the only relevant thing I get is 'openal' when I run things like - for i in openal plib openscene simgear \ flightgear ; do dpkg -l |grep $i ;done |fmt -tu I have used, and tested them when I do _NOT_ want to download and build yet another of these 2, thus when building in say ~/fg/fg14, I can reuse say my builds in ~/fg/fg12/install/[plib|osgvers]... And likewise there are options - BOOSTPATH=path BOOSTLIBS=path to point to where BOOST is either installed or 'staged' (not built or installed)... And a very, _VERY_ important one these days :- FGDATADIR=path to _NOT_ re-clone this massive block multiple times ;=)) time and space... However, at present you have to do MANUAL updates of such sources if the path is outside the 'root' build... and I think it will stay that way... As you may have learned, once a build completes successfully, some 'configuration' information is written to ~/bin/makefg-version.conf file, so you do _NOT_ have to remember to re-input such paths when it is run again, again, and again... Of course, with care you can manually adjust this 'conf' file... but it is easy to mess up the simple parsing that is done... so not particularly recommended ;=() And that is why there is a option NO_CONF, to tell the script to ignore any 'configuration' file information, when you want to really 'change' the setup drastically... Lots of options ;=)) over 80-90 at last count...

From Durk's suggestion, and the excerpt above it sounds like the multiplayer server might function in the manner of an RTI for a limited set of object model types ( unless we want to include submarines, tanks, bad guys, etc, etc... ;-) ) What you cited above is something that an RTI should implement in the end to be maximum scalable. But, you can implement an rti with just fewer of these options working. Much more than the above, the spatial indices implemented in the rti regions will be a huge benefit, since you will only recieve the messages that are relevant near the region of your interrest. Also the way an rti provides time management and time stamped messages, is benefitial. This enables hard syncronized hla federates, exchanging data at relatively high rates with the least possible communication latency. Regarding the ongoing threading discussion and the amount of cores an avarage cpu has today, an rti will provide a way to implement components of the simulation in a single threaded way, living in its own process. This can be done while still having a deterministic and tight coupling with other federates simulating in the same federation. This kind of coupling is required for example for a good simulation of glider towing for example. However, a quick search indicates there is an open source HLA on sourceforge License is Apache License V2.0, no idea how that compare to GPL or LGPL, but might be worth a look-see. Whatever, it is going to take time and effort (cost) to make FG compliant amd/or turn the multi-player server into an RTI clone or play-alike. And perhaps it would add a bit of formalism to the FG development track. :-) There is also one, at http://developer.berlios.de/projects/openrti/ Which is subject to envolve. But appart from that, the API is standardized by an IEEE standard and used with commertial simulation systems as well. Simgear also already has some rti abstraction library that should help to implement hla federates. Flightgear git already has an alternative multiplayer implementation in place that uses hla. But that is only thought as a proof of concept. The next step is probably to provide a seperate hla federate that runs the ai traffic and feeds that into an rti federation. All I did here started using the above hla implementation. So this one already works for this kind of stuff. So, there is already something in place, and I think that its definitely worth keeping that in mind.

Re: [Flightgear-devel] YASim issues
Ok success. It does rest slightly off the ground at the nose ... i removed the fake gear and all the mstab objects (clever use of mstab , by the way :)) , and still the same results... I have to admit I've never noticed this behavior before.

Re: [Flightgear-devel] release discussion
2011/4/15 ThorstenB bre...@gmail.com: Ok, not sure what has changed there, but is it important enough to be migrated to 2.2? I know it's tempting to make all the new features available right now (I'd like to see my new TCAS in the release, we've had 2 JSBSim updates, new HLA support, tank properties, joystick reloading, of course many many really nice Aircraft updates...). But they are not release-blocking. Last 2.2.0 fixes were applied on February 19th. I'll have a look at the commits on next/master since then. Anyone else aware of missing and release-blocking commits apart from the Models subdirectory? cheers, Thorsten Hi Thorsten, Yes, a bug fix has been committed to fix instant replay with JSBSim aircraft (bug #294) https://gitorious.org/fg/flightgear/commit/11320e6b008eb85b8dff66a137f671743cc04580 I think it should be applied to 2.2.0 as well.

[Flightgear-devel] props protocol problem
The props data protocol ls command has a problem: there's no way to
determine that its output is complete (unless we use a timer, which
would mean that all ls commands would suspend the client for the time out
duration).
I'm proposing to add a lsx command, similar to ls, but that will
terminate its output with an empty line.
In props.cxx, replace:
if (command == ls) {
with:
if((command == ls)||(command == lsx)){
and add:
if (command == lsx){
push( getTerminator() );
}
at the end of the branch.
