The Pi B3 has a 4core ARMv8 CPU, which is compatible with v7 code, so the driver works OK. Previous Pi's (including the Pi Zero) have an ARMv6 core, so installing the driver leads to a non-working system. ** the Open GL driver seems to have been written for the ARMv7 instruction set of the B2.

However, in Feb 2016 the first full OpenGL GPU driver became available, although only for the Pi B2 (full OpenGL won't run** on anything less than a B2, despite the fact that all Pi's have exactly the same Broadcom VideoCore IV GPU)īy mid 2016, the Open GL 2.1 driver was more or less fully working on the Pi B3 (which was released in Feb 2016 to replace the B2) and Stellarium was now achieving decent frame rates = in fact on the B3 it can actually achieve greater than 10 fps, no doubt helped in part by the Pi B3's 400MHz GPU (all other Pi GPU's, including B2, are only 250MHz) OpenGL was thus running on the Pi CPU in 'emulation' mode i.e. For now, I would suggest sticking with Jessie for Stellarium Much of below is from Daniel Chote's web page Getting Stellarium to work on the Pi B 3įor years various attempts have been made to get Stellarium running on the Raspberry Pi, however before mid 2016, even when success was achieved the frame rates were so appallingly low - seconds per frame, rather than frames per second - that it was a waste of time The problem is that Stellarium uses OpenGL, not the cut-down ES version that runs on the Pi GPU. However this seems to be matter of 'hit and miss', and, when a new OS is released (Stretch) it's often a matter of starting again.

It can (and has) been done with (some) version of Jessie. In short, running Stellarium means getting the 'right' combination of graphics libraries etc. This is quite normal in the Linux world where it rakes a while for the bugs to be 'worked out' of every new release Stretch OpenGL emulation speed can be inceased from 1/4 to 1/2 of Jessie speed by 'rolling back' some of the 'core' graphics modules also had probelms with Stretch ( see here) Users of Kodi, another heavy Graphics orientated app. In 2017 we got Stretch (with the 'experimental' VC4 OpenGL Driver), however the 'software emulation' speed dropped to 1/4 ( see here). Next, you need a version of Stellarium that will use the OpenGL hardware driver - which (initally) meant building it yourself.įinally, you will need to solve the remaining 'compatability' issues (things like 'text' display (font rendering), Planets 'flickering' and NEO/Meteor plotting killing the frame rate), however the Forums will usually help you find a solution.

So whats the problem ? Well, as usual with anything Linux, it's finding a 'compatible' set of modules that will actually work together to deliver a practical working solution We start with the need for the hardware (GPU based) OpenGL driver (by default, the Pi comes with a cut-down 'OpenGL ES' driver, with full 'OpenGL' supported via software emulation)Ī GPU based OpenGL driver exists, but only for the Pi B2 / B3, however it is (still) 'experimental' - which means you have to install (or 'enable') it yourself (although it's no longer necessary to compile it from source yourself :-) )

These days, even a cheap PC video card will have over 100 'cores', whilst the Pi has only 2 ! However, the Pi desktop is a lot simpler than the multi-display 'aero' garbage used on the PC, so those 2 cores CAN deliver decent graphics speed on the Pi. Stellarium makes massive use of the OpenGL graphics libaries - which, on a PC, will be supported by the GPU hardware on your video card. Pi Stellarium If you must have Stellarium, it can be done, however it's actually easier to get KStars working on the Raspberry Pi - see my previous page Why Stellarium is such a pain to get running on the Pi
