Hilbert Space Filling Curve for Julia

HilbertSpaceFillingCurve

Bindings for Doug Moore's Fast Hilbert Curve Generation. Windows is not supported.

Usage

Convert the linear index d into ndims-dimensional coordinates p :

p = hilbert(d::T, ndims, nbits = 32) where T <: Integer

Convert the ndims-dimensional coordinates p into the linear index d :

d = hilbert(p::Vector{T}, ndims, nbits = 32) where T <: Integer

All coordinates are positive integers (zero included). The number of bits nbits determines the precision of the curve, and the algorithm work under the constrain:

• ndims * nbits <= 64

Libdl not in dependencies

Received this warning this morning from julia-1.4.

[ Info: Precompiling HilbertSpaceFillingCurve [515b7ef8-bac0-55e1-a220-237e90591ccc]
┌ Warning: Package HilbertSpaceFillingCurve does not have Libdl in its dependencies:
│ - If you have HilbertSpaceFillingCurve checked out for development and have
│   added Libdl as a dependency but haven't updated your primary
│   environment's manifest file, try `Pkg.resolve()`.
│ - Otherwise you may need to report an issue with HilbertSpaceFillingCurve
└ Loading Libdl into HilbertSpaceFillingCurve from project dependency, future warnings for HilbertSpaceFillingCurve are suppressed.
