     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.
