[Algorithms] Hilbert curve

[Pierre T. <p.t...@wa...>]

Hmmm,
Is it possible to do something like a 3D-to-1D mapping from a point to a
position on the Hilbert curve ? If so, how do I do this ? Would it be
related to the way textures are swizzled ? If we can do that for textures,
can we extend the process to 3D ?

(which would give a good hash key for spatial clustering I suppose)
