Goxel is an open source voxel modeler.
Something went wrong. Please try again.
At least somewhat available for GNU/Linux.
You can script a build for it to render.
If you don't have it installed yet, just enter "sudo apt install goxel && goxel" on the terminal, and you will be running it in a few seconds.
Works nicely with Apple Pencil.
Finding help on e.g. using materials is missing or not easy to find.
