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
