# HilbertCurve

HilbertCurve[n]

gives the line segments representing the n -step Hilbert curve.

HilbertCurve[n,d]

gives the n -step Hilbert curve in dimension d.

# Details and Options • HilbertCurve is also known as Hilbert space-filling curve.
• HilbertCurve[n] returns a Line primitive corresponding to a path that starts at {0,0}, then joins all integer points in the 2n-1 by 2n-1 square, and ends at {2n-1,0}. »
• • HilbertCurve takes a DataRange option that can be used to specify the range the coordinates should be assumed to occupy.
