There exist so called "7 elements of art" which help you see like an artist.
It's a simplification since it's known that the "line" for instance, does not exist in nature.
Pen Pictures and how to Draw Them, by Eric Meade (1895), p.4
However, simplifying what we see in simple, understandable blocks, help us a lot when drawing...
...and when we do research in sciences,or when we try to solve a complicated problem in general.
We like to simplify complexity.
(vertical, horizontal, wavy, diagonal zig.zag or z-line)
(reading suggestion: Line: 7 Elements of Art )
(organic - natural, fluid, does not easily fit into mathematics; Geometric - mathematical formulae)
(the sense of touch)
(How dar or light an object is)
(illusion of distance, depth, close-far; )
(an object's shape in the 3 dimensions)
(you got it,uh?)
