.SH DESCRIPTION
|
| 16 |
.I Thf2rad
|
| 17 |
converts one or more GDS things files to a RADIANCE scene description.
|
| 18 |
The material names for the surfaces will be those assigned in GDS.
|
| 19 |
The
|
| 20 |
.I \-n
|
| 21 |
option may be used to give a name prefix to all the surfaces.
|
| 22 |
The
|
| 23 |
.I \-r
|
| 24 |
option may be used to specify a radius for line segments.
|
| 25 |
By default, this value is zero, which means that lines will be ignored.
|
| 26 |
By setting it to some positive value, cylinders of the given radius
|
| 27 |
will represent lines.
|
| 28 |
