Blender on Raspberry Pi
In a hot weather with multiple laptops running in the same room, the last thing I wanted to do was render, which I did and instantly the cooling fans turned on, result, the room turned uncomfortably warm.
Ten minutes later, I gave up on the render process as I did not want to sit in this oven and decided to fire up my Raspberry Pi 2, and checked to see if a build of Blender is available in the repository, turns out there is a built not the latest built but has everything I need for the render.
I highly recommend doing this on a Raspberry Pi 2 or higher, as it has sufficient amount of RAM for decent render and CPU that can handle BVH(Bounding Volume Hierarchy) duplication without any issues.
Announcement: I will be publishing the result of the benchmark once they have been completed, you can subscribe via email to get notified or leave a comment.
Installing it is like another application.
sudo pacman -S blender
sudo apt-get install blender
The good thing about Blender is it has CLI support, which lets you render without firing up the GUI.
blender -b file.blend -o /render/frame_##### -F PNG -f -2
Let’s break down the flags used above.
-b (render in background without GUI)
file.blend (location of the blend file to be rendered)
-o (Location to where the render will be saved)
-F (Override the image format specified in the blend-file and save to an PNG image.)
You could also do preview renders, that are quicker than offline render.
