That is similar like SpaceX tracking during Falcon 9 launches. I like that MFD package. I like to see tracking above ground. How high altitude current launch is.

I checked but I already have Nvidia drivers v580 and MesaGL interface installed. I think that MesaGL cause orbiter to crash. I will figure out later. I installed Fedora 44 from scratch on my other drive. I was able run Orbiter without any issues. I recompiled them with new GCC 16 compilers.

Yeah. I am using vanilla install (fresh install). Should I install Nvidia drivers or so?

When OpenGL client starts, it just displayed blue screen but, immediately crashed. Here is log file did not say anything wrong I decided to run gdb and it crashed in CloudTile::Render();

I tried to run orbiter on Ubuntu 26.04. OGL client crashed after launching from menu. There are no log files. Ubuntu 26.04 replaced old X11 code with new Wayland for HDR support.

Ok, got it now. Thanks for info. Yes, that called zodiacal light that was reflected from interplanetary dust. Full moon reflected 12% (albedo .12) sunlight and shines on Earth. At night, I can see anything without flashlight! Astronauts were able taking a picture of night side of earth.

Yeah. Solution is using HDR (10-bit color depth).

I had seen new photos from Artemis II lunar flyby. Astronauts took some photos during solar eclipse. I saw the dark crescent on northwestern moon. Sun shines on earth but it reflected 30% of sunrays (albedo .30) and shines on moon. I googled and found some information. Also, something...

So impressive! Blind astronaut/pilot can fly/orbit!

I read a book called "3D Engine Design for Virtual Globes". I learned a lot about globe rendering. Read page 164-169 about RTC (relative to center) in the chapter 5 (Vertex Transform Precision). I noticed that Orbiter uses RTC method to eliminate jittering. With RTC method, geometry object...

Folks, That is very new to me when I research some. I now learned that NASA launched rockets into the parking orbit. I noticed that rockets do not follow orbital path so that its orientation is fixed around orbit. Rockets were slowly flipped back. When they are ready to leave earth, they...

I resolved all matrix problems by using my Wolfman Alpha Pro account. Multiplying matrices are easily confusing. I analyzed them by using minus and plus, swapped cos/sin, etc. Corrected formula: // Set rotation matrix for local horizon frame // for right-handed rule (OpenGL). Points // to...

Thanks for let us know. I noticed that math code is not interpreted anymore in my other topics.

I re-installed Ubuntu 25.04 on my new SSD drive with faster USB 3,2 gen 2x2 enclosure. Required libraries for Ubuntu: sudo apt install doxygen libfontconfig-dev libglfw3-dev libsndfile1-dev libglm-dev libopenal-dev But I tried to compile orbiter but got some linking errors. make[2]: *** No...

Yeah. We can implement 128-bit fixed. 96-bit field is kilometer unit that covers Milky Way galaxy and nearby galaxies so that it is micrometer accuracy, when we are entering system, set astrocenteric coordinates to (0, 0, 0) at relative 128-bit fixed. I got an idea myself. Update: I looked...
