WebJan 25, 2012 · A Hilbert curve is a type of fractal curve; here is a sample: I can't remember why I was working on this. Possibly I was anticipating that 16 years in the future, during an unusually mild New England winter, I would be looking for a blog topic. Anyway, there are several interesting ways to code up a Hilbert curve generator. ... WebThe figure above shows the first three iterations of the Hilbert curve in two ( n=2) dimensions. The p=1 iteration is shown in red, p=2 in blue, and p=3 in black. For the p=3 iteration, distances, h, along the curve are labeled from 0 to 63 (i.e. from 0 to 2^ {n p}-1 ).
