In particular about the irregular terrain mesh - how is it ... Our current terrain engine was great in the late 1990s (when MSFS still had a flat world), but it's pretty stale now, mainly from a lack of interest and the difficulty of understanding the code. It's actually deteriorated in some ways -- note that all the Great Lakes have been forced to sea level now, so that Lakes Huron, Michigan, and Superior are in deep gorges, and all the cities beside them are perched on cliff faces (that wasn't happening a couple of years ago). I'm not sure that we should really be maintaining our own terrain engine any more, though -- we should concentrate on aircraft models and flight dynamics, and try to interface with an existing engine. That depends on where your interests lie, I suppose. A flight simulator has specialized needs from a terrain engine: good close-up detail for near or on- earth operations, terrain stretching to a far horizon, no-pause loading of terrain from everywhere on the round earth, accurate material properties for ground polygons. I don't know of any free project that offers this. One promising prospect is Demeter, which works with OpenSceneGraph (already supported by FGFS): http://www.tbgsoftware.com/index.html Unfortunately, Demeter itself seems to have gone a bit stale -- some of the links from the site don't work any more, and it won't compile with the latest version of OSG. It does, however, support LOD and lots of other nice stuff (check out the screen shots!). Maybe someone should take it over if the maintainer has abandoned it, or fork it if the maintainer hasn't but is stalling on new releases. It doesn't do round-earth at all... The best thing we could do in FGFS, in the meantime, would be to isolate scenery-engine dependencies so that it's easy to switch to a new engine when it's ready. That's not a bad idea; isolating the scenery engine would make it viable as an independent project as well. I think we have the expertise, both on the production / GIS side and the programming side, to create a first-class world terrain and terrain engine that would be taken up by other projects too. I personally want to work on this, but I need to help get our OSG house in order first. I'll start a Wiki page with some of my ideas (which aren't very original).

[Flightgear-devel] Colombian Air Force virtual T-37
Hi, I received the following request from a university group: VOLTA is a research group of Militar Nueva Granada University, in this moment we are development a project for Colombian Air Force. In reference with a e-mail send by JHON JAIRO PALOMINO LOSADA (it was send in 25-oct-2007), We need the T-37 for FSX with all the instruments at the control panel and painted with the Colombian Air Force logo and colors. If you can do it, send us the quotation (how much is it, time and payment way) This requirement is very important and urgent for us, we thank for its aid and quick answer Now since I don't have time to do it, nor the expertise to create a FSX model I wonder is someone here might be interested in this proposal. I wouldn't mind if someone would make some bucks out of this using my T-37 model (both FDM and 3d model) provided that the changes to the existing T-37 model will be backported to the FlightGear model as well. Anyone who is interested could contact me privately for the contact information. Erik - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Re: [Flightgear-devel] Demeter (was Re: FlightGear terrain engine)
Hello, Few thoughts as FlightGear moves to osg there is a nice virtual terrain project which is integrates with osg. The site for the project is http://www.vterrain.org/ and some papers are here http://www.vterrain.org/LOD/Papers/. Personally I like Thatcher Ulrich adaptive quadtrees approach ( which allows to load chunks in runtime and thus it is possible to ) the approach is implemented in Soul Ride game which source could be obtained here http://sourceforge.net/projects/soulride/ ( this one specific implementation does not feature loading new chunks but I seen the java code with the functionality. anyhow there are quite a bit of approaches which are presented at http://www.vterrain.org/LOD/Papers/ and some are more hardware friendly than adaptive quadtrees.

This worldwide automatically = press the button I'll do the rest is really far from working as you describe yourself. Actually there is a lot of knowledge necessary to do the work and even if Martin will finish his part you have to go through the training process for every LS7 picture as far as I understood all. But your work will result in a big step forward to a better scenery, together with tasks from other people, and even going through several procedures before you'll get the result is nothing compared to the manually Landsat7 picture scanning like I did for OSG areas and obviously many OSG people do - even if OSG has a Tools with JOSM and the LS7 background-area function a tool we are only dreaming of. submit that to the service again and retrieve automatically classified vector data I doubt that this will help most of the scenery-developers/users as long as you cannot process these data due to that cannot compile, cannot use TerraGear problem.

Cheers Another tip: you better use a group in the .ac (3D) model and use the group name when you want an animation on all objects together, doing so create a different branch in the tree. If you specify all the objects namely in the same block, you may have difficulties to animate them separately later. You can also use another method which is a bit more verbose: a select animation with the condition, and later in the xml the material animation without condition. You will have in your .ac (3D) file of the panel the lamp off and the lamp on. then in the xml you can select the 'lamp on' object upon a property. Again use separate block for single objects called by their name or a group of them if needed. Alexis - This SF.net email is sponsored by: Splunk Inc.

I think the problem here is about sceney _data_ generation as much as about the scenery engine itself. The sceney generation process is overly complex, many people who tried didn't get far for one reason or another. Then, we have experts who know how everything ties together but simply don't have the time to maintain the code. Finally, when scenery actually gets generated, it either lost a lot of details or worst, has a lot of errors. There are a few opensource libraries that are dedicated to the features that you have mentioned. GTS, for example, can do continious LODs as well as CSG. The great thing about using existing libraries is that these libraries are purposely designed, dedicated to what they do, and are maintained by experts, instead of being hacks that are written once and hardly get looked at afterwards. So, not only will we able to cut holes into the terrain for runways, we will also be able to do so better and much more efficiently. Ampere - This SF.net email is sponsored by: Splunk Inc.
