hilbert alternatives and similar packages
Based on the "Data Structures" category
Do you think we are missing an alternative of hilbert or a related project?
[Image of 8 by 8 Hilbert curve](images/hilbert.png)
This is not an official Google product (experimental or otherwise), it is just code that happens to be owned by Google.
How to use
go get github.com/google/hilbert
import "github.com/google/hilbert" // Create a Hilbert curve for mapping to and from a 16 by 16 space. s, err := hilbert.NewHilbert(16) // Create a Peano curve for mapping to and from a 27 by 27 space. //s, err := hilbert.NewPeano(27) // Now map one dimension numbers in the range [0, N*N-1], to an x,y // coordinate on the curve where both x and y are in the range [0, N-1]. x, y, err := s.Map(t) // Also map back from (x,y) to t. t, err := s.MapInverse(x, y)
The demo directory contains an example on how to draw an images of Hilbert and Peano curves, as well as animations of varying sizes for both.
go run $GOPATH/src/github.com/google/hilbert/demo/demo.go
and the following images are generated.
Simple 8x8 Hibert curve:

Simple 9x9 Peano curve:
