Project Skybolt Client Development

[Gondos]

@Gondos I pushed some updates:

• updates to the Skybolt v1.2 branch to fix which fix the FFT ocean compilation errors, as well as some bug fixes
• updates to OrbiterSkyboltClient master branch to build with conan, as well as some bug fixes. Build instructions are in the README.md.

Thanks for the update, but still no luck with the conan build. Got lots of undefined references as if OpenSceneGraph was not linked against correctly :

The engine compiled with a custom makefile and this one patch though :

I'm updating my linux branch to use cmake again, when I'm done I'll try again with your latest client version.

Thanks for the update, but still no luck with the conan build. Got lots of undefined references as if OpenSceneGraph was not linked against correctly :

I had the same issue linking to the static OSG libraries on linux. I'll need to investigate further, but a workaround is to configure conan to build OSG as a shared library:

conan install ${workspace} -o openscenegraph-mr:shared=True --build=missing

 

[BHawthorne]

Looks great. Excited to see how this develops. Any possibility for multi-display external camera rendering?

Still no luck, I tried building it inside a fresh debian11 docker image but it still fails during the link.
Maybe it's a distro issue? Debian is not that bleeding edge... What kind of linux environment are you using?

I run the skybolt CI build on ubuntu. In case it helps, here's the build script and ubuntu build log.

OrbiterSkyboltClient 1.0.2 Released




Release Notes
Improvements

• FFT ocean support
• Orbiter land masks are now used for water shading

• Improved terrain normal mapping by accounting for curvature of earth
• Virtual cockpit dynamic mesh components (e.g switches and gauges) are now supported
• Improved particle stream shading
• Improved volumetric cloud LOD blending
• OSG log messages are now logged to standard orbiter log

Bug Fixes

• Fixed incorrect particle velocity bug
• Fixed crash when terrain textures not present
• Fixed bug where incorrect terrain tile LOD levels were selected
• Fixed bug where shadow map resolution in config file was ignored
• Fixed issue where clouds occlusion appeared unrealistically dark
• Fixed bug where HUD was covered by volumetric clouds in some cases

Coming to you soon: "Orbiter Naval Simulator"

 

[OvalDreamX]

Wow, as soon as the client supports normal and specular maps, we will see some awesome looking spaceships

 

[Majid]

This is freaking amazing!

 

[GLS]

I'm getting several errors like

000000.010: FRAGMENT glCompileShader "Shaders/Particles.frag" FAILED

000000.010: FRAGMENT Shader "Shaders/Particles.frag" infolog:
ERROR: 0:1683: 'OUT' : failed to expand macro

and I'm not getting the beautiful visuals, but instead bland meshes, no terrain or clouds and a gray rectangle covering the top-right quarter of the image.

I appear to be getting a water-planet. Did I miss something in the install?

That is what I get at altitude, and a very dark surface at sea level.

 

[Gondos]

This looks awesome, I'm gonna have to buy a new video card now ^^
Concerning your engine, how do you cope with the huge distances involved in planetary rendering and z-buffer accuracy? The D3D clients do some tricks by disabling z-writes/z-tests, playing with the clipping planes and rescaling the planets on the fly...
Do you do something similar or is a 24bit z-buffer enough to deal with the dynamic ranges involved?

In Orbiter_NG.cfg, could you check if PlanetTexDir is set to the 2016 Texture directory? (In my case C:\Orbiter2016\Textures\ )
I remember having a similar issue before.

On my end, all the paths are the default ones ("./Textures/", etc), and replacing them with the full path changed nothing.

I have NVidia GForce GTX1060 6GB card - seems it is not suitable for this client? I have OpenGL at least 4 version... SpaceEngine, for example, works flawlessly.

 

[DaveS]

I'd love to try this out but I lack the knowledge to set up a proper test environment. Could someone write up a tutorial similar to what I did for SSU ( https://www.orbiter-forum.com/threa...date-ssu-installation-for-orbiter-2016.27769/ )?

 

[DaveS]

So I tried to get this built by following the instructions on the Github page, but it failed out with the following error message. It seems to fail at the conan install OrbiterSkyboltClient step.

Thanks to supersonic71, I was pointed to pre-built package available on the Skybolt Github page so that bypassed the build sources step. It certainly looks good, but while using the standard Delta-Glider/DG-S Ready for takeoff scenario, I get very low frame rates, in the 20's. Also, from orbit the clouds look very blurry and low-res, I have attached a screenshot of this. Is this expected at this stage?

 

[gamer19]

Dave, which Orbiter version did you used with Skybolt ?
