Next-generation scenery generating?

Yet download failed here - not so strong pptp connection cuts off with sources as github, while to set proposed l2tp is quite story. Don't know, maybe upgrade to next Fedora version will help - manually compiled latest NetworkManager dropped previous installation to unworkable state anyway.

BTW, I noticed at wiki something as that user would need to download 70Gb prior see anything - at first thought, if it's true then it's wrong solution for sure.

70Gb is the total size of all DEMs covering the whole world. Of which only the 3rd low res you need the whole world to see anything. This is about 7 MB The 1x1 tiles at high resolution is the huge part. This is why I am focusing on Hawaii - it has good mountains, and is an island. The dropbox tarball is 45 MB, and covers Hawaii in all five levels.

The next delivery will be 3 levels. Unsure how big it will be - less levels, but tiles in each level are larger. I hope to have the update this weekend.

Everything seems to be set, but I get just water. Log is:

Previous engine works, runned it at same fps from stop to stop with whole view.

Did You follow Your own instruction for test? That got to be made at least once. Seems to be that You forgot to add "git checkout topics/new-scenery" or something as that.

Though with such addition simgear is compiled, while flightgear produces an

Code: Select all: CMake Error at utils/CMakeLists.txt:39 (add_subdirectory): add_subdirectory given source "gdalwarp" which is not an existing directory.

error. Gdal package includes

Code: Select all: /usr/bin/gdalwarp

it's file, not a dir. What's next?

Hi Vitos,

Thanks for trying this out.

As far as the gdalwarp directory in the flightgear utils dir, that does look like a mistake. I didn't add the gdalwarp dir to the commit as it was mostly just the source from gdal. I was compiling my own version of the gdalwarp utility (with my own added debug ) to help debug the warping done by the demconvert utility. This should not have been committed to the repo.

I will remove the reference from utils/CMakeLists.txt.

As far as only seeing ocean - from the log, it looks like the terrain engine is still using the tile-cache, not the new engine. Can you confirm you have this in your cmd line:

--prop:/sim/scenery/engine=pagedLOD.

Maybe post the full cmd line, and I will try it as well. I can confirm the shell script on the wiki is the exact script I run when testing.

Pete

Well, seems to be I compiled not Your branch, but just common "next" branch at first. So Your engine was not even compiled, started too of course. Then I switched to branch, and got an compilation error.

With removing of gdalwarp ifdef compilation started, let's see what it will bring.

Ok, still water, but something about Your engine is at logs:

ok - looks good - did you download the hawwiidem tarball into /home/vitos/Src/ ? if so - just use that as the extra scenery path - it will append /DEM to the path.

Terrain init - dem path Path "/home/vitos/Src/DEM/DEM" has NO LOD Levels

Directly under /home/vitos/Src/DEM/ should be:
level_01
level_02, etc...

if you use --fg-scenery=${HOME}/Src/ in your command line.

and - yes - I am starting a bit over the water here. you may need to climb a bit higher to find Hawaii

next up - I want to flatten PHNL (at runtime), and allow a fixed wing aircraft to start on the ground.

Well, You made it a bit nonstandard way - compare with way FGDATA is set. There You set path with directory name, while at You case - without.

Ok, now I do not have a water too. Just pale blue screen with things as

at log. DEM was get by link and extracted, directories are presented.

Wait... Ok, something is there.

Nice!

The delay ( and pulling in successively detailed terrain around the aircraft ) is because I still don't have a way to know when scenery loading is 'done' - so The dialog box disappears before scenery starts loading.
This makes any aircraft that needs ground interaction at boot kind of impossible. i need to determine when the highest LOD around the aircraft has been loaded by OpenSceneGraph before letting the dialog close, and FDMs to init.

The lots of could not open file errors are expected - I've only included a small sample set around Hawaii. Ideally, it will be downloading the tiles from terrasync.

The scenery path is the same as current scenery path setups. We already append Terrain for the tiles, and Objects for scenery objects - I am adding DEM for height data, and will be appending Landclass for the landclass rasters.

The quality of the meshes ( that are not pushed yet ) are better than what they appear with that dem, but I want to get the normals and skirts done before next push.

Got Your idea. Ok, yet all looks as needed for initial state.

Good. And why it could not be done before, can I ask noble public?

Well, it still has a long way to go. The visuals at close range are pretty bad

The infrastructure I'm basing this off of ( SPT tiles ) has been in simgear for > 2 years. The idea was to simplify our normal .BTG tiles for middle LOD ranges, then use the regular grid / blue marble for really distant range.

Unfortunately - simplifying the corrine landclass tiles was very problematic. When the idea to use raster images instead of vector based landclassing arose, using a regular grid became an option. I am still unsure how coastlines , and vector roads/rivers will work. but, as the wiki is tiltled - it's experimental

At now it looks better than EarthView, dont take much fps - so at least for orbital rendering that will go.

Actually it's better than major engine with its zigzag rivers too - it just dont have anything as that.

I have a progress update. I will be pushing the new mesh soon. It still has an issue at 12x12 degrees and higher where tiles meet - looks like some artificial valleys when seen from space. I am pretty sure it's a roundoff error when generating the grid. I haven't tracked it down, yet. I wanted to make some more progress so I started the landclass rasterization script.

It is a fairly simple script that uses GDAL tools to categorize, chop, merge, then rasterize the images for each tile. It took 80 minutes on my computer to rasterize Hawaii. ( if this holds, it would take 75 days for the whole world. )

The categorization step only needs to be done once, and if we ever accept custom shapefiles from scenery designers, we would expect this step to be done before submitting - it basically encodes the landclass into each shapefile geometry, so when we merge - each shape retains its landclass encoding.

Here is what Hawaii looks like in QGIS post rasterization ( with band1 = red, band2 = green, band3 = blue ) = actual encoding will be more like band1 = landclass code, band2 = smoothing, etc...

And here's zoomed in near Honolulu airport:

I will start trying to map each tile to its own image in flightgear next week.

and here's an image of the new mesh resulutions - highest res == SRTM3

Sweet... Looking forward to seeing this textured :-)

It would be nice to have some "like" button here at forum.
