FSGenesis v2 Mesh to Fix Airport Plateaus

Recommended Posts

If you're partial to FSGenesis products like I am, it looks like Justin is getting ready to release v2 of his mesh for FSX which should also fix the FSX airports sitting on plateaus. Can't wait...:-jumpyhttp://www.fsgenesis.net/ Version 2 Features . . .The most prominent feature of version 2 is the addressing of the plateaus on which many airports are sitting in version 1. This plateau effect is not caused by the terrain mesh, per se, but by the flat-airport limitation of FSX. However, FSGenesis has developed a reasonably satisfactory proprietary method to deal with this issue globally without having to fix many thousands of individual airports manually.Additionally, vertical resolution has been increased from 1 meter in v. 1 to .25 meter in v. 2, which will create a more pleasing display of terrain elevations while eliminating any terracing effects seen in version 1.

Looking forward to seeing how this turns out. I've haven't had the mesh installed for awhile as I fly mostly bush and the smaller airports seem to be effected most by the plateau issue.

I, too, had uninstalled the mesh as I just could not live with the airports on plateaus.

Maybe I misunderstand Justin's email, but not all elevation differences have been fixed. Some have and he has provided an improved method to report the mismatches, but I don't think a universal fix was found. Bob..

JustinThis is great to hear - I like your mesh a lot but, as many have noted, the plateaus were always a bit jarring. I don't suppose you could give us a short description of how you have decided to get around it? If I had to guess, I would think/hope that you have produced a more gentle slope such that the airports still sit at their current height but the mesh now includes an artificial gradual adjustment to this level around the airport instead of stepping up/down to it.I look forward to your update!RegardsDavid

This is great news. I'm just curious. Will water bodies also be addressed? I've noticed several lakes and rivers etc. where the water is too low and the terrain drops straight down. And even a few that are on plateaus. I was really hoping to finally enjoy some decent flying around Lake of the Ozarks in Missouri but it looks really bad. I'm using UTX also so I don't know if that has anything to do with it.

It is due to the lake elevations being incorrect--a feature not controlled by the terrain mesh.The dataset that Microsoft used for lake elevation data is...well, let me say it is not super accurate. For areas outside the USA, it is only generally accurate.High resolution terrain mesh only brings out these dataset inaccuracies even more (the pits, plateaus). Some people would rather avoid the plateaus and pits by not running high res mesh. I think that is folly as the positives far outweigh the negatives.RhettAMD 3700+ (@2585 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2gb Corsair XMS 3-3-3-8 (1T), WD 150 gig 10000rpm Raptor, WD 250gig 7200rpm SATA2, Seagate 120gb 5400 rpm external HD, CoolerMaster Praetorian

Hi David,Well, after many tens of hours pondering and brainstorming the problem, and probably a hundred hours of futile trial and error (mostly error) with the keyboard and mouse, I arrived at a relatively simple, albeit time-consuming solution. Recalling a conversaion with Adam Szofran at last years devcon in Redmond, the light bulb popped on. Adam had told me then that they "fudged" the terrain for 1 km outward from the airport background polygon.So, it simply becomes a matter of my punching holes in my source data for a 1 km radius surrounding each airport. This allows the default terrain to show through within that radius, while the FSG terrain is shown everywhere else.I have more or less automated this process, but my poor computer still takes 4-6 hours to accurately process each of several hundred large chunks of source data. As such, I can process about 6-8 square degrees per day running around the clock.So rather than processing it all, then releasing everything at once, I am going to release the areas for download as they are processed and completed then when the whole thing is done, I will ship whatever optional media is ordered. The first area (0101, for those familiar with the way FSX files are organized--western Washington. Northern Oregon for those who aren't) is completed awaiting uploading, and I am now processing 0102, hopefull ready over the weekend. I will then follow working west to east until the contiguous 48 states are completed. Then will come Canada and Mexico, then the rest of the world.Stay tuned for more details . . .-------Justinhttp://www.fsgenesis.netHigh Quality Scenery for FS200x

JustinThanks for taking the time out to provide a good description. It makes sense - I'm guessing that the difference between the FSX mesh and your mesh is more gradual and less noticeable - I look forward to seeing the final result!It just so happens that your first upload is the area I happen to be flying around in FS Economy (http://www.fseconomy.com/ for those who haven't tried it out - it's free and fun and will get you flying in places you hadn't thought of and in planes you might have neglected...). I should be able to see the results fairly quickly although it will now make trying to find those small airports a lot harder - as it should be. :)CheersDavid

Justin, would more processing power be of any help? I'm perfectly willing to give you access to my PC during my down time (GMT), if you have the technical knowhow.

Funny, I was thinking the same thing. I have a 4ghz quad core with 4gb ram. If it's automated I could run it for 9 or 10 hours a day while I'm at work.

same here. Justin, you need to "BOINC" your application and we do the crunching for you :)

Thanks, guys. However, we would run into a licensing snafu with my GIS software, in addition to a logistical problem of getting over 100 Gb worth of source data out to you all.But the gesture is moving to say the least.Another solution would be for several hundred of you who haven't yet obtained the FSX Bundle Special, get it > today < and I'll run out over the weekend and get a cutting-edge quad-core system with NVIDIA

LOL...OK, Justin, you've convinced me. But I do have one question. I asked on your forum but no answer yet, so I'll ask here too. If I buy and install the Mesh and Landclass packages, will I see a significant frame rate hit? ("Significant" being more than 5 frames per second)If the answer is no, I'll buy your bundle in a heartbeat! Today!

As a user, no. Run, don't walk, and buy it. I'm a 'Galaxy' member if that gives you an indication of the regard I hold for Justins products

What PPSFA said. ;-)You shouldn't see a significant hit. Depending on your horsepower,maybe a frame or two.I always recommend turning off the frame rate counter and just enjoying the view. :-)-------Justinhttp://www.fsgenesis.netHigh Quality Scenery for FS200x

Justin,With the automated way you deal with airports on the front end, will custom airports and AFCADS have any affect on the plateau after v2 is installed?

OK, you've convinced me. I'll go buy it.Now let's see a bunch more of you do the same. :D
