Web1st iteration there are 4 elements which map to (0,0), (0,1), (1,1) and (1,0) 2nd iteration has 16 elements, by dividing each point into 4 sub quadrants. The solution looks for which quadrant the element lies in and based on that solves the x,y recursively. 0 Show 3 replies … Both the true Hilbert curve and its discrete approximations are useful because they give a mapping between 1D and 2D space that preserves locality fairly well. This means that two data points which are close to each other in one-dimensional space are also close to each other after folding. The converse cannot always be true. Because of this locality property, the Hilbert curve is widely used in computer science.
