A method for determining virtual visibility is disclosed. The method
includes modeling at least one object in a virtual space and plotting at
least one surface from a first predetermined location relative to the at
least one object within the virtual space. The method further includes
identifying at least one interference between the at least one object and
the at least one surface. The method still further includes determining a
first characteristic of the at least one interference and determining if
the first characteristic is within a predetermined range.
