As far as I know, nope. GEM requires full OpenGL while RPi supports OpenGL ES only. GEM needs modernization to support ES and maybe Vulkan or something similar at some point but it's a *massive* effort likely.

I suggest writing a graphical frontend in a different environment such as OpenFrameworks and communicate between Pd and your app with OSC.

Hello
Anyone knows wether it is feasible nowadays to run GEM on a Raspberry PI and process some 2500 pix_data grey value in real time at 25 fps ?
Thanks !
:)
