sition matrix,
such as calculating the inverse, will produce a dense matrix that cannot
be stored in a similarly optimized manner. Instead, the dense matrix
will have the same memory requirement as the first figure above. These
calculations quickly become impractical with even moderately-low amounts
of landscape data. The following figure illustrates how many landscape
cells could be practical with consumer hardware when these calculations
are involved. This is under <em>ideal</em> circumstances; in practic
