Re: [Flightgear-devel] [ANN] OSG - Improved Weather Radar
While there's so much hacking happening wrt to radar instrumentation, I'd like note a small observation. There seems to be a small, but noticeable, inconsistency about the heading displayed. You can see this if you enable the showing of a tacan source in the radar and its corresponding data/symbol whatever box. They appear to point into different directions. I suspect both informations get derived by ways taking the magnetic variation into account differently. The combinations of radar echos/groundradar/radar compass rose look pairwise consistent though. But on further guesstimating I tend to think all that rl atc happens with the magnetic heading in mind (thus rwy 28 in KSFO for example), so perhaps the radar screen should reflect this by rotating accordingly. I'm not even sure if that would change the difference I talked above (and if so, in the right way). For now I fear I cannot dig deeper into that, but perhaps this can a serve as pointer fo some you guys already busy hacking that part of fg. Thanks to you anyways for the great job. regards K.

I haven't looked at the radar stuff yet, so I'm just going from what you've said here. VORs are slaved to a certain variation, presumably the magnetic variation at the time they were put into service (or last updated). But as the magnetic variation in any place changes over time, the VOR variation can differ (sometimes substantially) from the compass heading.

IANAATC but I know the headings given out over the air by ATC and ATIS, etc. are all magnetic, so you're possibly right. If nobody else has ATC experience or friends, I have a former ATC acquaintance I could ask any questions to. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Oh, ahem, err, a tacan source here being the Nimitz off the coast of San Francisco, and indeed its heading seems to have no part in the drawing of the symbol. Furthermore a normal tacan navaid doesn't possess a heading anyways. I perhaps just wished it would somehow improve my other point. *g* regards K.

(It's also not my graphics card driver, as Qt4 has no problems with RTT.) Perhaps this isn't a new bug after all. Yes, that's my assumption. I've spent some time on that but still haven't found the cause. Tender-to-texture works in fg/osg and QT4, so it doesn't seem to be a graphics card driver problem. 3D clouds also use RenderTexture but don't cause crashes. So, what's the difference? Answer: the clouds never call the RenderTexture destructor! If I comment out delete rt in ~FGODGauge(), then I don't get a crash either. Unfortunately, I couldn't find out if the destruction is really needed (calling glXDestroyPbuffer()). The RTT instruments are only destroyed at exit, and maybe the destruction of the GL context frees everything, anyway? BTW: the TestRenderTexture app in simgear/screen/ does also not crash, despite calling glXDestroyPbuffer() for mode changes (Return-key). But it does also not destroy the RenderTexture class at exit! So is this an acceptable method? Would commenting out delete rt be the solution for 0.9.11?

This is by far not complete, but I post it here so that interested people can give it a try and to give an opportunity for code review. *** This is for OSG only *** Prerequisites: Vivian's and Tim's wxradar I have split the patch into logical changes: 1. tower.diff: Loads the tower position from apt.dat.gz, falling back to the current calculation method if that information is not present. 2. runways.diff: Loads the taxiways into memory as well. 3. autohide.diff: Adds support for an autohide flag in 2d panels. For compatibility reasons this defaults to true. When false, the automatical hiding of the panel based on view direction is disabled. 4. ai.diff: Changed AIAircraft and AIMultiplayer to use AIBase::_callsign member. Renamed _getPath to _getSMPath as the corresponding set method is _setSMPath. Added _getPath to return model_path. Added const attribute to _getCallsign. 5. groundradar.diff: a new owner-drawn instrument that paints the current airport layout into a texture 6. wxradar.diff: added labels in data mode. Needs more work. 7. fg.diff: contains all of 1-6, above, for convenience. 8. ATC.diff: changes to Syd's atc-tower aircraft. This goes into data directory. Also make sure to copy the new panel-bg.rgb.

Perhaps someone could enlighten us? The new 3d clouds have potentially lots of good features like rain and turbulence, but I'm not sure we use them.

Perhaps someone could enlighten us? The new 3d clouds have potentially lots of good features like rain and turbulence, but I'm not sure we use them. When I first incorporated Mark's code, was unable to get my head around how to add objects to the plib scenegraph and with the help and patience of Curtis and others was finally able to get something working. However it was no where near the best solution, but we lived with it. When a new developer provided an integrated plib solution with a different cloud rendering approach, the hack was moved to the attic. Having reduced the entire 747 project down to two PCs (one for the cockpit and one for the Flightgear scenery on three projectors) was thinking of a third machine to produce enviromental effects, like a wind field using smoothed metar data to avoid the artifical shearing when changing stations, real-time cloud generation based on atmospheric conditions, improved earth/gravity model using Bessel functions, moving the AI to a dedicated machine and using the MP service, etc, etc. lots of ideas, very little time.
