Apparently running DOOM in Altium wasn't stupid enough, so now it renders with actual PCB primitives
Yesterday I posted Doomium running inside Altium Designer.
The first version used a window over the PCB editor, which wasn't stupid enough.
So now there are two more renderers. One draws DOOM using actual PCB fills, and the other uses colored PCB regions.
Yes, these are real objects in the PCB document.
