As well as blender… I need to create art work on my Pi?
Hi,
You’ll need to install a desktop 1st (eg: LXDE desktop). Once completed:
For Blender and Gimp, you can install it with apt:
apt-get install blender gimp
You may have issues with openGL rendering with Blender on the RPi. There is a OpenGL (ES I believe) driver floating around for the RPi: Raspberry Connect - Trying out OpenGL on Raspberry Pi 3
For Doom, i think it may need to be compiled. Under the section “DOOOOOOOM!”: Setting up Raspbian (and DOOM!) - SparkFun Learn
