It was first described by David Hilbert in 1892. Applications of the Hilbert curve are in image processing: especially image compression and dithering.

Hilbert Curve -- from Wolfram MathWorld

WebA space-filling curve (SFC) is a way of mapping a multi‐dimensional space into a one‐dimensional space. It acts like a thread that passes through every cell element (or pixel) in the multi‐dimensional space so that every cell is visited exactly once. Thus, a space-filling curve imposes a linear order of points in the multi‐dimensional space. WebI have never seen a formal definition of the Hilbert curve, much less a careful analysis of why it fills the whole square. The Wikipedia and Mathworld articles are typically handwavy. I suppose the idea is something like this: one defines a sequence of functions fi(t): [0, 1] → R2, and then considers the pointwise limit f(t) = limi → ∞fi(t). iowa state university dining balance
