Outputting to a 3D LED Cube

I’m building a large scale 3D LED Cube. Madmapper will be running the LEDs. Is possible to have Notch output slices of 3D space? I’m thinking render layers with orthographic cameras that step in for each layer along with a black plane for each “slice”. This approach seems very heavy tho… Am I missing a more efficient method?
