Re: FlightGear & Pi4

I have been using the Ubuntu 64-bit FG and have found it to be stable and better features. Can not say that it is faster than the 32-bit Raspbian but it does seem a wee bit better. Can get frame rates in the 30 fps. That is not in dense scenery areas. I like the launcher. A new version will be coming out soon.

When using the 64-bit Ubuntu, keep an eye on the keyboard LEDs for Num Lock and Cap Lock. It likes to turn one of them on, just before you type in your password, etc.. After it is all booted and your logged it the Locks stay put.

Last night I was able to compile and build FG 2020.2.0 for 32-bit Raspbian. Looks good. The sun is fixed and the guide wires for towers. Looking forward to trying it on Ubuntu 64-bit. My wild guess would be that, in a few months, we will have a 2020 version in the Raspbian software repository.

Thought that I would, occasionally, post some screen shots.

Cool, more progress.
Have not tried FG for months, it looks better, nice screen shot.
What version of Mesa is that Raspbian running?

FG can use Tablets as displays, through WiFi?
Running HTML on a browser?
A Pi could do the same thing?

I do not recall it being a dependency, that doesn't mean it isn't.

Yes, Phi.

Yes, Phi.

I use a Pi3 A+ and a touch screen to use Phi. My understanding, at this point, is rather simplistic.

I just read that MESA was involved with FlightGear. They seem to talk about other stuff much more. Next, I hope to compile the 64-bit Ubuntu version. There are option when compiling so maybe some more room for improvement.

Try the new 64bit Raspberry Pi OS.
FlightGear installs and boots, That's about all I have tested.
May even work better on the 8GB Pi4?

Lots of new 64bit stuff to play with now.

I used the menu software installer, FlightGear was in the games section.
Will be interesting to see if multiple Pi's can be hooked up together for cockpit instruments and multiple displays.

They are working on the new FlightGear LTS 2020.2. The OSG 3.4, that is in the Pi 64-bit package installer, seems to work with FG, so no reason to patch and compile OSG.Download_and_compile.sh worked well to compile 2020.2.1. Still has the square sun. That can be tweaked, however I have not figured out how. Maybe all the work on the Pi 3d stuff will help.

Looks pretty good.
Have not tried FG for a while.

Wondering now if a bit more performance can be tweaked by going to Vulkan soon?
https://vsg-dev.github.io/VulkanSceneGraph/
https://github.com/vsg-dev

Code: Select all

[[ 67%] Building CXX object src/vsg/CMakeFiles/vsg.dir/viewer/Trackball.cpp.o
/home/pi/VulkanSceneGraph/src/vsg/viewer/Viewer.cpp: In member function ‘virtual bool vsg::Viewer::acquireNextFrame()’:

                 result == VK_ERROR_FULL_SCREEN_EXCLUSIVE_MODE_LOST_EXT)

/code]

Close but no cigar yet:D 

Bookmarked to go back to this VSG later.
OSG is used in lots of things, VSG should give a tiny bit more performance.
Anyone in FG using Vulkan?

There was one mention of updating something so that Vulkan could be used. I think 3d stuff will keep getting better for Pi.
