NAME

       mgf2meta - convert Materials and Geometry Format file to Metafile graphics

SYNOPSIS

       mgf2meta [ -t threshold ] {x|y|z} xmin xmax ymin ymax zmin zmax [ input ..  ]

DESCRIPTION

       Mgf2meta  converts one or more Materials and Geometry Format (MGF) files to a 2-D orthographic projection
       along the selected axis in the metafile(1) graphics format.  All geometry is  clipped  to  the  specified
       bounding box, and the resulting orientation is as follows:
            Projection     Orientation
            ==========     ===========
            x         Y-axis right, Z-axis up
            y         Z-axis right, X-axis up
            z         X-axis right, Y-axis up

       If multiple input files are given, the first file prints in black, the second prints in red, the third in
       green  and  the  fourth  in blue.  If more than four input files are given, they cycle through the colors
       again in three other line types:  dashed, dotted and dot-dashed.

       The -t option may be used to randomly throw out line segments that are shorter than the  given  threshold
       (given as a fraction of the plot width).  Segments are included with a probability equal to the square of
       the  line  length  over  the square of the threshold.  This can greatly reduce the number of lines in the
       drawing (and therefore improve the drawing speed) with only a modest loss in quality.   A  typical  value
       for this parameter is 0.005.

       All MGF material information is ignored on the input.

EXAMPLE

       To project two MGF files along the Z-axis and display them under X11:

         mgf2meta z 0 10 0 15 0 9 building1.mgf building2.mgf | x11meta -r

       To convert a RADIANCE scene to a line drawing in RADIANCE picture format:

         rad2mgf scene.rad | mgf2meta x `getbbox -h scene.rad` | meta2tga | ra_t8 -r > scene.hdr
