mgf2meta - convert Materials and Geometry Format file to
Metafile graphics
mgf2meta [ -t threshold ] {x|y|z} xmin xmax ymin ymax zmin
zmax [ input .. ]
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.
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.pic
