It's not that bad an analogy: the location of things *is* uncertain in that, for any one coordinate, it will "jump" to one of eight positions that are the nearest representable locations at a given precision and distance from origin. When measuring or comparing between two locations they could diverge in opposite directions or converge doubling the normal error that you'd expect form the "cube". And in certain rare cases the error is larger. Then the effects of calculation error propagation make it worse, etc. chris > > _______________________________________________ > vos-d mailing list > vos-d@interreality.org > http://www.interreality.org/cgi-bin/mailman/listinfo/vos-d > _______________________________________________ vos-d mailing list vos-d@interreality.org http://www.interreality.org/cgi-bin/mailman/listinfo/vos-d
