Cutting sequence

From HandWiki
Short description: Records individual grid lines crossed ("cut") as a curve crosses a square grid
The Fibonacci word is an example of a Sturmian word. The start of the cutting sequence shown here illustrates the start of the word 0100101001.

In digital geometry, a cutting sequence is a sequence of symbols whose elements correspond to the individual grid lines crossed ("cut") as a curve crosses a square grid.[1]

Sturmian words are a special case of cutting sequences where the curves are straight lines of irrational slope.[2]
