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
