BTW : I've seen some MSFS scenery that had street lights along a major road - it looked incredibly real and is a great navaid at night.

Re: [Flightgear-devel] 18th Century city texture
Would it not make sense to determine a "visible range" attribute automatically based on size? These issues may already be addressed by some LOD systems anyway. Any LOD people out there? I do agree that certain custom objects should have user defined priorities. I can't see a computer determining how important a certain object is to VFR. Designers would really have to agree on a way to determine this though. What one person considers a major landmark, someone else may not. I forsee a need for a set of general conventions so that everyone is on the same page. Mayber instead of assigning a numeric level to an object, it would be better to assign it several classifications, and let individual users decide what weights to assign various characteristics. For instance user a may feel that a medium sized object with large uniquenes of design is more important where another would rate a large sized object with medium uniquenes of design higher.

It would probably be lots of work, but this way, we could easily enable 18th century textures for interval ranging from let's say 1700 to 1800. And we would be the only flight sim supporting that too :). I think you misunderstood what I was trying to tell. This is a texture for cities which are created around the 18th century, but still exist. Those type of cities look quite different from modern cities like most US cities. To get actual 18th century look one would need the scenery for that time, not the textures in particular.

I've successfully remastered a Knoppix CD and made my own favor of Knoppix, added some programs, removed others, and before all: set my own desktop theme (focus under mouse!). It wasn't really difficult. But I don't feel like making a fgfs CD. The problems with licenses of different proprietary graphic cards aren't such a great motivation.

I've already been investigating the Knoppix a few months ago - but for whatever reason I didn't find out how people are extracting the necessary base for sevral projects that use Knoppix. Probably someone has to ask Klaus directly. I failed to spend more time on that because my resources are very limited, but now that you ask directly I will contact him this weekend.

I suspect it may have something to do with Nasal, since one of the broken bindings is x, X and ctrl-X, and it has only been broken since the 'view' script came into the CVS tree. I wasn't following the beginning of the Nasal thread. Is there a startup option I need to enable Nasal scripting to work? Nope. Just the latest version of SimGear/FlightGear/base_package should do.

I think the FDM trees could be marked non-polling upon creation. I don't see a way to use these trees in aircraft without being bound to this particular FDM. If there are properties inside the FDM specific tree which are needed for FlightGear they need an alias to somewhere in the FlightGear tree (IMHO). Erik BTW.

[Flightgear-devel] LiveCD for FGFS - suggestion
For those people who enjoy this kind of challenge (I don't have time): If someone has (or will have) a script for making a Knoppix style CD of FGFS, I think the capability is directly relevant for teaching/instructional use. The CD, when starting FGFS, might load a default configuration and then give the user the option of running the sim with an automation sequence. Ideally, the sequence should be easily replaced if the CD is re-burned. Around the USA, Aviation Safety Counselors give safety related talks to pilots and AMTs as part of the FAA's Wings program. While the materials for the presentation can be generated from scratch, it is usually easier to take advantage of existing videos and other materials. We could provide such materials, in the form of an FGFS LiveCD with such a scripting file, to both assist in the talk and to enable attendees to practice at home. While I don't have time to work on the CD image, I'd be happy to make up scripts so FGFS can be used in a Wings presentation, eligible for credit. Pilots who take part in Wings need to attend at least one 2-hour session every year. I'm sure that, with the progress the project routinely makes, we'd have no trouble creating at least one presentation topic every year.
