osgEarth with airport lighting and structures

[poweroftwo]

Here are some screenshots from the latest iteration of osgEarth integrated into Flightgear. Features include airport and runway lighting and surface clamped structures from TerraSync. Has some imperfections but overall works well. With all ground features enabled, can be a resource hog though so requires a capable machine and a good bit of memory. Only tested Windows 64 bit with 4GB Ram so far.

The functionality is near completion. Not sure there will time to get all complete and tested prior to 3.2 release but will attempt to get all cleaned up soon so that a merge request can be generated.

Ah, you picked the worst case comparison... with procedural texturing and in the new Southwest texture scheme, it actually looks much nicer in FG native

But good work, I'm glad to see this is still going on strongly, many people are interested in this feature and there's a lot of questions coming when this will be available.

simgear compiled perfectly, but flightgear cannot be built on my PC:

Code: Select all

/home/juanvi/FlightGear/flightgear/src/Viewer/OsgEarthHeightField.cxx:508:26: fatal error: PrintVisitor.h: No such file or directory
 #include "PrintVisitor.h"
                          ^
compilation terminated.


I cannot identify the missing library, google is of no help

(I checked out your OsgEarthNext branch)

Edit: I'm taking a plane in a few hours and I won't be able to run more tests until Monday.

Latest was in a different branch. But now is in OsgEarthNext branch).

True, I have not updated my FG in a while. I will soon for better comparisons.

Nice work Jeff!

I had to change the mentioned line to this with that old version, but seems to be fixed now:

Code: Select all

#include <osgUtil/PrintVisitor>

Which git repo is this build currently living in? I can't see it in the main FG one.

These should be the public links to the flightgear / osgEarth repositories (note that latest development is found in OsgEarthNext branch)


Use this version of osgEarth:
• git clone -v -b OsgEarthNext https://github.com/poweroftwo/osgearth.git osgearth

• git clone -v -b OsgEarthNext git://gitorious.org/fg/simgear-osgearth.git simgear
• git clone -v -b OsgEarthNext git://gitorious.org/fg/flightgear-osgearth.git flightgear
• git clone -v -b OsgEarthNext git://gitorious.org/fg/fgdata-osgearth.git fgdata
• git clone -v -b OsgEarthNext git://gitorious.org/fg/fgrun-osgearth.git fgrun

Hi Jeff,

I've been using osgEarth for a while now (nice work!). There is one big problem though; every now and then tiles suddenly drop to sea level, loosing all elevation data. The number of tiles involved changes while moving around. A certain tile can be at sea level in one instance and the next second it's back to normal. I've been seeing it with a build from a few weeks ago as well. It only seems to happen on relatively detailed tiles (as in high LOD levels). I haven't been able to really pin point the issue, but maybe you have an idea of what could possibly be wrong. I'm using the ArcGis earthfile. There are unfortunately no related errors in the logs. Another problem is that the tiles are always lit, regardless of the time of day.

I've used current osgEarth from Git, is that correct, or should I use a specific version?

Cheers,
Gijs




EDIT: The lighting problem is also present when osgEarth is disabled. I'll rebuild from scratch, as this looks quite messed up; even tough I like the cartoon style

[poweroftwo]

There have been some major changes to osgEarth in the past few months that don't integrate well in FG yet. Please use this version instead:

git clone -v -b OsgEarthNext https://github.com/poweroftwo/osgearth.git osgearth

(I am pretty sure that this OsgEarthNext branch is actually the main osgEarth 2.5 tag) but use the above to ensure is the same as what I am building to.

Correction - this branch is not the 2.5 tag but instead is progress made that contains improvements in the fog shader.

Also, I am about to re-work the airport light clamping code, as I am unsatisfied with the performance. For the larger airports, the processing is taking far too long.

I adjusted the poweroftwo OsgEarthNext branch to point to a slightly older rev of osgEarth in order to fix some lighting issues with the terrain.

git clone -v -b OsgEarthNext https://github.com/poweroftwo/osgearth.git osgearth

Nice, my zero-elevation issue is solved now! I'll try the new (well, old) osgEarth revision to see if the terrain is now correctly lighted and dark at night.

EDIT: Terrain is dark at night now; awesome!

Odd. I get linker errors when trying to compile flightgear against this version of OsgEarth

sounds like you might not be in the correct branch. Confirm that you are in OsgEarthNext.
