NAME
       bdy - boundary curve finder

SYNOPSIS
       bdy [precision]

DESCRIPTION
       Bdy  is	a filter used to find boundary curves in Geomview objects.  The program reads a geomview object from standard input and prints the
       resultant vector object to standard output.  Bdy finds the segments of the vector by first converting the given object into a polylist (See
       anytooff(1)).   Then,  it  finds  all  edges  used  once  and only once in the polylist and combines these edges into a vector object.  The
       optional precision arguement specifies the maximum distance between vertices that are to be considered identical.  By default, it is set to
       0.0,  indicating  that the vertices must be numerically identical.  It may sometimes be necessary to set it to a higher value to compensate
       for floating-point error.

       The vector object is always black.

BUGS
       The vector object is not a particularly compact representation of itself, since it contains many 2-vertex segments which could be combined.
