field_lines - field lines is a mapper module which converts a 2D field in an object of lines and planes. This module will create black lines (in optionally i- or j-direction) with a 'no-lighting' plane below it, so the field will look like a serie of non-transparent graphs.

Description

       The module uses a 2D scalar field to build a mesh.
       The mesh consists of lines, where the value in the field
       is used as the z-position of the vertex.
       Since the "lines" option in the geometry viewer
       creates a transparent object, lines in the
       back stay visible and the object does not look clear.
       In order to make lines in the back invisible, a plane is created
       below the created line.
	
       This way the object looks like a serie of graphs positioned
       next to each other.
       You can choose to make only graphs in the i=constant or the
       y=constant direction or both.
       In order to make the lines good visible, you might use
       'anti-alias' or a translation of the planes object in the z-direction.
       Since sometimes only the values in the j-direction are correlated,
       this is a very nice module to show the corresponding graphs
       in one picture.
