Re: [Flightgear-devel] Trying to get more performance out of the 3Dclouds!
IIRC clouds were moved into bin 10 to improve appearance vis-à-vis particles. If we put clouds back into bin 9 and particles remain in 10 all the cooling towers, chimney efflux, aircraft contrails, exhausts etc. are drawn after the clouds i.e, in front. Rather looks as if we can have realism or framerate but not both. Are these assignments runtime-changeable? If so, one could use a simple criteria to get it (roughly) right. * particle effects associated with an aircraft are always drawn in front (they must be nearby to see them anyway) * aircraft contrails are always treated as clouds (they are clouds) * ground-based model effects are drawn in front if the current view is below some decision altitude, and they are drawn at back if the aircraft is above (with the decision altitude being the lowest cloud layer) This set of rules should get so much right that the exceptions don't really matter.

[Flightgear-devel] flightgear merge request #14 and airportinfo()/navinfo()
Greetings all, After a number of discussions on the forums and e.mails I've put a patch together that extends the nasal interfaces for airportinfo() and navinfo(). As the patch outlines these are backward compatible, they only look for optional extra parameters, otherwise existing nasal code works as before. Could someone have a look at https://gitorious.org/fg/flightgear/merge_requests/14 and review. While it doesn't support all use cases that I had wanted (because some parts of the API for the nav info I couldn't work out) it does help extend those two functions, primarily to help FMS/FMC glass cockpit builders.

This might solve your problems, although it is not a one size fits all solution. I'm still getting many error messages at EHAM - but it's better now. It's starting ok and I'm hearing AI sounds. Nice :) However, XML conditions for AI aircraft have no effect. All AI sound samples are played unconditionally as soon as the aircraft is in range. That's the problem of the AIModel code that models hardly any properties suitable for sound playback. It should be extended and the config file should be updated to match the changes. play once AI sound samples are also played continuously. I think it's caused by an issue with your last update. Attached patch restores the effect of the XML conditions for me - and also play once samples work as expected. Not sure if that's the correct way to fix it though... Not entirely no.. it looks like the looping setting gets lost in the process, I'll take a look at it.

Rather looks as if we can have realism or framerate but not both. Are these assignments runtime-changeable? Not that I can see at the moment - right now particles are hard-coded to go into bin 10, and the others are shader based which can be changed relatively easily - but not during runtime. If so, one could use a simple criteria to get it (roughly) right. * particle effects associated with an aircraft are always drawn in front (they must be nearby to see them anyway) Sort of true - but this will generate odd effects in tower views. * aircraft contrails are always treated as clouds (they are clouds) Yes - true - but they are particle based so they will follow whatever heuristic is appropriate for aircraft above. So they will almost never be right. The persistent contrails are shader based, and can go into whichever bin the clouds go, and will work fine, except they will not necessarily match the particle based contrails. * ground-based model effects are drawn in front if the current view is below some decision altitude, and they are drawn at back if the aircraft is above (with the decision altitude being the lowest cloud layer) We make no distinction between types of particles - they're all the treated the same atm and get bunged into bin 10. This set of rules should get so much right that the exceptions don't really matter. So you can see why the decision was made to lump them all together into 10 and let God, sorry OSG, sort them out. And so it does by and large, making a pretty good job of it, but it takes its time over it. Catch 22 or what?

[Flightgear-devel] OT: git question
Hey all, I have a quick question for the git experts among us. I've done some googling, but I must not have my search query phrased exactly right, or maybe I don't quite know the right git terminology for what I want to do. Hopefully it's simple enough. I have a local project here that uses git and has a single master branch. I had a wild and crazy idea that I wanted to explore, but knew it would involve a lot of code refactoring and rearchitecting -- I didn't want to mess up my good working tree -- especially if the idea didn't work out. So I created a branch: git checkout -b newidea I then pushed forward with the new idea inside this branch, made several rounds of changes and many commits to this new branch. Now I really like my new idea and I want all this work moved back into my master branch. What's the best way do to this? Could I rename the master branch to be pre-newidea or whatever I want to call it, and then rename my newidea branch to master? Or is that bad git practice? Would it be better to merge all the change in my newidea branch back into master? If so, how would I go about doing that? Thanks!

You want to merge your branch back into master. merge is the right word: git checkout master git merge newidea done. If the merge creates conflicts, git will tell you so. To fix them, simply edit the files and add them to the index (git add fixed_file) and when you are done do a git commit. A merge usually creates a new commit anyway, since it's a new version of your source tree. Could I rename the master branch to be pre-newidea or whatever I want to call it, and then rename my newidea branch to master? Or is that bad git practice? Would be possible as well, but branching and merging are the basic tools in git and they are fast, simple and work quite well. And they create no confusion if someone else got your old master branch.

You will get the bilboard effect for free. We have a queriable limit in the maximum supported point size which nobody guarantees to be really high. But in reality point sprites can get up to render buffer size for almost any GPU I know. The open source radeon driver does glClear by drawing a screen sized point sprite... When using the binary fglrx driver there are known problems with point sprites (not sure if anybody ever figured out the real cause) so if we switch to point sprites we should be careful to keep the current method as an alternative for the benefit of fglrx users. Well, that's the runway lighting problems? The reason is well known to me. We do triangles in point mode using back face culling to get the directional lights. Enabling point sprites in this mode is something fglrx does not like since some time. The open source driver can go well with this without any fallbacks. This one has other prolems, so just suggesting the oss drivers is not yet a real option. I dont think that this kind of problems also apply to a possible cloud implementation. What you would do for clouds is much closer to the particles in osg. And these also work for fglrx. Mathias -- Cloud Computing - Latest Buzzword or a Glimpse of the Future?

If we put clouds back into bin 9 and particles remain in 10 all the cooling towers, chimney efflux, aircraft contrails, exhausts etc. are drawn after the clouds i.e, in front. Rather looks as if we can have realism or framerate but not both. Hmm, If I change the renderbin to 9 and instantiate a non sorted one, I am still draw limited here. Also If I look at the application runtime profile I see functions dominating that happen during draw in the driver. There is no sorting function high in profiles. May be OpenGL drivers that draw faster are depth sorting limited. But being draw limited this is what I can see here. But, the question is how many cloud drawables do we have? The render Bin sorting bottleneck - if we run into this - is O(log(n)*n) with the n= number depth sorted drawables. Which means we need to have a huge amount of cloud drawables that this effect dominates. Ok, looking into the Cloud drawable implementation, I believe that your almost first response is probably the easiest. Just without point sprites, just improoving what is currently done: Try to put that multiple draws into a single draw using array objects. Make sure that you still get a 'fast drawable'. YOu can verify this by asking the geometry if osg::Geometry::areFastPathsUsed() returns true. That is mostly: do not use any index arrays. The only indices which may be worthwhile are the indexed primitives sets. Sorting inside the drawable is then done by either redoing the arrays or probably better by using an indexed primitive set and reordering the indices.
