Re: [boost] range, multi-dimensional

Have a look at VSIPL++ ( Vector, Signal, and Image Processing Library 
http://www.vsipl.org/ ), the spec is here ( 
http://www.hpec-si.org/spec-1.0-cand-revD.pdf ), and an open source 
implementation is available if you're interested. VSIPL++ supports 1, 2, 
and 3 dimensional containers. Domain objects represent sets of indices 
that correspond to a sub-view of the container. An N dimensional Domain 
contains a 1D domain for each dimension. If nothing else it may be 
helpful to see how others have approached the problem.
