Anyway, the gist is that you're essentially using the magic of mathematics to channel aether. Geometries, specifically. The inks used to draw the geometries are metallic in nature that are conducive to the flow of aether. An arcanist visualizes the design in their head--these tend to be complex, hence the image as a sort of reference--and thus casts the spell.
