[Flightgear-devel] First results of terrain texture generator
Hello! Around 6 weeks ago, I came up here with the idea to represent ground features through textures rather than through terrain mesh polygons for more detail and easier modification (which is of course not my own idea, but it's definitely a practical one and not yet implemented in FlightGear). I'm currently trying to develop a texture generator program which generates fake aerial images using the same ESRI shapefile data that is used for TerraGear scenery generation, and it is now for the first time able to produce some useful results. I'd like to present some images that were made with it, hoping that someone with knowledge about OSG and FlightGear's terrain rendering system might perhaps like them at least a little bit so that she/he might want to help me finding a way to get them into the sim. They use FlightGear's terrain textures, so it looks much like the current FlightGear scenery, but with curved roads and rivers and a few other improvements (more to come, I have some further ideas and this is still a very early stage of development).

Vivian I share , Vivian's remarks =Regarding animations i noticed some strange behaviours with osg when the model is made of an others others (sub)models hierarchy , mainly when we have more than two level stage (sometime working, sometime not :) ) I only noticed it , i can't explain it. =Regarding heat haze ,when digging into the osgparticle:: programme, we could probably have something which could replace that nice effect. Up to today, i am not able to give a good script, may be a better expert than i am could write within a short delay that script. -- Gérard http://perso.orange.fr/GRTux/ - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Flightgear-devel] glitch in runway searching

I think it would be better to explicitly check for runway type instead of checking for not taxiway. Any comments? Whatever you see fit. I checked in the fix using == runway, as suggested by Csaba, but if anyone encounters the problems about which you speculate below we'll revisit the issue. Thanks, Tim !taxiway was just the last hack after playing around with different possibilities. Reasons as far as I remember were: 1. Not to mess with some possible(?) helipad or seaplane port equivalent of a runway. That would of course be invalidated by the existence of any other ground structures that are not runways like apron, whatever (apt.dat version 850) but I did not intend to rewrite the whole runway class just for that fix and so didn't really check into it deeply. 2. I guesstimated, probably mistakenly, that checking for something not being equal to a given string might be a tiny bit faster, esp. as there would be a lot more taxiways than actual runways on every airport. I had some vague suspicion that some part of the infamous stuttering every couple of seconds I sometimes experienced might be related to the ai aircraft trying to search their runways but further testing was inconclusive on that. hth K.
