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.
