.SH DESCRIPTION
|
| 15 |
|
|
.I Mgf2meta
|
| 16 |
|
|
converts one or more Materials and Geometry Format (MGF)
|
| 17 |
|
|
files to a 2-D orthographic projection along the selected axis in the
|
| 18 |
|
|
.I metafile(1)
|
| 19 |
|
|
graphics format.
|

|
|
All geometry is clipped to the specified bounding box, and the
|
| 21 |
|
|
resulting orientation is as follows:

If multiple input files are given, the first file prints in black,
|
| 32 |
|
|
the second prints in red, the third in green and the fourth in blue.
|
| 33 |
|
|
If more than four input files are given, they cycle through the
|
| 34 |
|
|
colors again in three other line types: dashed, dotted and
|
| 35 |
|
|
dot-dashed.

|
|
The
|
| 38 |
|
|
.I \-t
|
| 39 |
|
|
option may be used to randomly throw out line segments that are
|
| 40 |
|
|
shorter than the given
|
| 41 |
|
|
.I threshold
|
| 42 |
|
|
(given as a fraction of the plot width).
|
| 43 |
|
|
Segments are included with a
|
| 44 |
|
|
probability equal to the square of the line length over the square
|
| 45 |
|
|
of the threshold.
|
| 46 |
|
|
This can greatly reduce the number of lines in the drawing (and
|
| 47 |
|
|
therefore improve the drawing speed) with only a modest loss in
|
| 48 |
|
|
quality.
|
| 49 |
|
|
A typical value for this parameter is 0.005.
