    One suggestion: There is Ajaja's SPICE for Orbiter module on GitHub so that this Orbiter can have full solar system with Pluto, etc. I got SPICE toolkit from NAIF website and you can compile SPICE into a shared library as spice.so. Ajaja's module can link spice.so for function calls like...

    Celbody modules with no source code

    I have SPICE toolkit. I downloaded 176 GB stuffs from NAIF website through wget. Ajaja provides SPICE interface module on GitHub so that you need SPICE toolkit to compile. I recommend making documents for developers how to get SPICE toolkit and build them into spice.dll or spice.so. I...

    Better Ephemerides, Rotation Models, and a Solution to X64 Builds

    Yeah. Astronauts will scream "Huston, we see planet teleport to other place!". I recommend larger ones for long space exploration. Thanks for providing Ajaja's Spice module on GitHub. I cloned it. I reviewed that and recommended making document about how to get SPICE toolkit from NAIF...

    Yeah. Of course, we could see Orbiter on iOS and Android platforms soon. They need to compatible with OpenGL ES.

    So impressive! It does not work on MSYS2 so that I have to use WSL2 or stand-alone Ubuntu.

    Wandering Earth

    I watched "Wandering Earth" on Netflix and "Wandering Earth 2" at cinema. Very interesting!! Scientists built giant thrusters on earth and move earth out of solar system for Alpha Centauri system before our sun is dying (expanding into giant). It looks impossible to me. Is that possible to...

    Problem Cannot Download SSU v4.2

    Yeah. I have the same problem with SourceForge but now found SSV on GitHub and cloned it. They should not remove that but should mark them as public archive so that future developer can fork that and continue.

    OK, I got it and will look into zip file package. Yes, Martin did that. That is same code (sigma equations) from VSOP87 package. I recongized that additional code is used with Calculus formula. R = f(sum) = cos(term) for position V = f'(sum) = -sin(term) for velocity That is in...

    I found VesselBuilder on GitHub but can't find GeneralVehicle. VB is written in C++ but uses a lot of Windows function calls. It needs to being changed a lot for compatible with cross-platform libraries like Qt, GTK, Gnome, etc. I also am looking some MFD modules for interplanetary, reentry...

    OK, hold on. I tried it on Linux but it did not work. I did try shared module as test program on MinGW and it only worked on MinGW under Windows. I will investiagate it later.

    I replied to XR limitation topics and explained about tiny panels. For match egdes, you might take a look on D3D9 client code. I saw match edge routines in D3D9 client code. Did you write OGLClient from scratch or where did you get from? Be aware about jittery issues when round-off errors...

    Problem Tiny XR2 panels in 4K resolution

    Today there are many 4K HDR monitors on market. That issue still needs to be fixed. I tried Linux version of Orbiter with XR vessels but my panel was still not stretched to fit and its text is too small to read. I have the same problem like that.

    Also I tried that DeltaGlider at moon but some part of landing pad are not on ground. Also I noticed that match edges needs corrected.

    No, Panel get stretched with Delta Glider that came with Orbiter. I tried XR1 but panel was not stretched. Same as XR5. Only Delta-Glider got stretched panel. Update: I checked XRVessels repo and there are XR*InstrumentalPanel.cpp/h files so that you can update codes to fit 4K resolution...
