bdy(1gv) bdy(1gv) 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 re- sultant 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, in- dicating that the vertices must be numerically identical. It may some- times be necessary to set it to a higher value to compensate for float- ing-point error. The vector object is always black. BUGS The vector object is not a particularly compact representation of it- self, since it contains many 2-vertex segments which could be combined.
