Right, it's about the pattern, not that specific image/design. Since the amount of infill between the walls can use existing infill patterns pretty much.
The 2nd example shows what a 3D design may look like. But a lighting infill example would look something like this, with 2 walls eliminating the outside seam, otherwise you can build up the bumps wherever needed to fully support a roof, just like lighting infill. https://imgur.com/0yUMlNk
