NAME
     lines to geom - draw a set of 3D line segments 

SUMMARY
     Name	   lines to geom 

     Type	   data input

     Inputs	   none 

     Outputs	   geometry 

     Parameters	   Name		   Type
		   data file	   browser

DESCRIPTION
     This module reads an ascii input file and creates a set of 3D line
     segments in a single geometry object.  The module expects the
     file to have an extention of ".xyz". 

     Each line segment is assumed to have the same number of vertexes.  
     Duplicate vertexes can be used to overcome this but they are not
     ignored in this version.

INPUTS
     none

OUTPUTS
     a geometry containing a poly-line object is output

PARAMETERS
     data file		-the name of the ascii file with the list of points
			 for the line segments.  File format is as follows:
			 <int_num_lines> <int_num_points_per_segment>
			 <vert1_line1x> <vert1_line1y> <vert1_line1z>
			 <vert2_line1x> <vert2_line1y> <vert2_line1z>
			 .
			 .
			 <vert1_line2x> <vert1_line2y> <vert1_line2z>
			 .
			 .
			 <EOF>



EXAMPLE
     Typical network usage:

     lines to geom
	       |
     render geometry
	       |
     display pixmap
