Re: [Flightgear-devel] A New Sun
Thank you for doing this.
I love accurate meteorology, sky conditions and astronomically correct
sky. It looks very photographic with the exception of the halo. One
thing that always bothered me was when the sun disc is close to the
horizon, the line seems too well defined. Where the extended sun glare
disc meets the horizon it is very sharp. Beyond that the fog obscures
the horizon line. Is there some way to blend the sun more smoothly
into the horizon?

Or, illustrated with some code:
fgfs:
static double calc_density() {
// stuff
return density;
}
void Whatever::bind() {
fgTie("/calculate/density", calc_density);
}
void Whatever::unbind() {
fgUntie("/calculate/density);
}
now you tell sg that it can have the density from /calculate/density,
and whenever sg or anyone else reads that property, the density is
calculated freshly (and only then).

Re: [Flightgear-devel] RFC: A new sun
Hi, I looked at the rain code and it seems a more elegant solution than what I've done so far. I just passed the needed info as elements of a struct which I filled with the same get-methods in renderer.cxx. However, as it appears you can only read and set the information in the property tree. But what I would need is a function I could call that calculates some values. So even when I would use the set-methods to put my data in the property tree, this wouldn't be adequate. The reason for this is that I'm considering the average density along the light-path. This is necessary because it can differ vastly depending on the planes position and results without this aren't realistic. For example, take two positions, in which the distance of the light-path is equal but the altitude of the observer is different. The sun will be much more yellowish for the observer at a lower altitude because the average density is higher and there's more scattering taking place. Also the light-path can go through areas of higher and lower density if the observer is at a higher altitude and the sun is setting. In this case the light first travels through low density arriving from the sun, then higher density at earth-level and then again traverses low density air at the observer. So only taking the observers density and the density at the top of the atmosphere in account is not going to act as a accurate substitute. To figure out the average altitude I determine the density at the observers position, the density at about 8-16 km (depending on the lat due to different thickness of the stratosphere at the poles and the equator) and the density at the half of the distance the light travels through the stratosphere. This gives a rough idea of the average density that is good enough for our purposes. So ideally I would have to pass an altitude to the function and it should return the density at that height. But then the environment code is in Flightgear. I could, however, put the code somewhere else in Simgear, but what's the sense to scatter basically the same type of functions around different parts of fg/sg? I don't know. Any Ideas?

[Flightgear-devel] Windows compile is twice as big, shakey and takes much longer to load
my windows compile of fg 9.10 is 6,626KB instead of 3,772KB, it also takes way longer to load --- but the unacceptable part is that went you scroll around the cockpit, the picture shakes. The orignal, smaller 9.10 precompiled version runs fine on my machine, anybody ran into this or have any ideas?

Re: [Flightgear-devel] [Fwd: LinuxWorld Expo London 2006 - Free space for .Org]
While you're at it, why not look for a spot at the Flight Simulator Weekend, Nov. 4 and 5, 2006, Aviodrome Aviation Museum, Lelystad. (That's the weekend following the Linux World Expo). As a simbuilder I already have a place there, but I believe there's lot more room for more people. Just have a look at www.fsweekend.com for more info. I've never seen a FlightGear booth there, and would certainly like to see one!

[Flightgear-devel] [Fwd: LinuxWorld Expo London 2006 - Free space for .Org]
The LinuxWorld expo in London, UK (Oct 25-26) is offering free .org booth space. Are there any UK based FlightGear developers/users (or people that might want an excuse to visit the UK) Alex, Trish :-) who might want to help setup and staff a booth for this show? FlightGear is often one of the more popular booths at these types of shows because many of the other booths have relatively "static" subject matter such as computer hardware, job recruiting services, business software, "obscure" software of mainly sys-admin or developer interest, and a host of other booths that are only worth visiting for the freebies, and then ta-da, you come around the corner and there's flightgear, a cool 3d application where you can sit down and fly interactively. You will here a lot of "Whoa, what is this..." type comments as people approach the booth (at least for the Texas shows.) :-) I'm sure there is a matching UK translation meaning about the same thing.

But most people don't understand that concept, and will always mix tabs into it. You need an editor that shows tabs, and you need to have style -- a requirement that most don't fulfill.

I'm not aware of any formatter that groks c++. And ultimately, developers won't like if they are forced to use any other style than their own. My only wish is consistency. Some people don't give a damn about the existing style of a file, and add code in theirs. This leads to files with mixtures of 2, 3, 4, 5, 7 spaces, and tabs, mixed wildly together. This is not made up! I've fixed several of those. There are files with 12 (twelve!) tabs in front of some lines. (Apparently, the author uses 1-position tabs.) Indenting *must* be rocket science. The only thing that is bad even if it's consistent: FSF coding standard. It looks like shit, is hard to read, and has no other purpose than being "different". It's a political coding style, not a rational one. I can't stand it and will eradicate it wherever I can. I'll never commit files in this style.
