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
