The input is either a single XML file, such as might be produced by |
| 33 |
|
.I genBSDF(1), |
| 34 |
|
.I bsdf2klems(1), |
| 35 |
|
or |
| 36 |
|
.I bsdf2ttree(1), |

or up to four scattering interpolation representation (SIR) files, as |

might be produced by |

A |
| 42 |
> |
.I rad |
| 43 |
> |
input file will be produced, whose name matches the root of |
| 44 |
|
the first input file but with any leading path removed (i.e., in |
| 45 |
|
the current directory). |
| 46 |
|
This RIF may be reused for subsequent viewing and rendering via |
| 83 |
|
Additionally, all the standard views that |
| 84 |
|
.I rvu |
| 85 |
|
defines will be available (e.g., "xZ", "zl", etc.). |
| 86 |

.PP |
| 87 |
+ |
Since a |
| 88 |
+ |
.I rad |
| 89 |
+ |
input file is created by the script, it may be used |
| 90 |
+ |
in subsequent runs as long as the temporary files remain. |
| 91 |
+ |
These are typically kept until the next reboot of the operating |
| 92 |
+ |
system, so re-running |
| 93 |
+ |
.I bsdfview |
| 94 |
+ |
with the same arguments will not require re-running |
| 95 |
+ |
.I bsdf2rad |
| 96 |
+ |
or |
| 97 |
+ |
.I oconv. |
| 98 |
+ |
Thus, start-up will be much quicker, unless the temporary files have |
| 99 |
+ |
been removed. |
| 100 |
+ |
In this case, the script may exit with an error indicating that the |
| 101 |
+ |
.I rad |
| 102 |
+ |
input file needs to be removed. |
| 103 |
+ |
.PP |
| 104 |
+ |
This input file may also be re-used directly from the command line using |
| 105 |
+ |
.I rad |
| 106 |
+ |
or |
| 107 |
+ |
.I trad(1). |
| 108 |
+ |
This may be useful for generating RADIANCE pictures corresponding |
| 109 |
+ |
to the above standard views. |
| 110 |
+ |
If no interactive run is desired, start |
| 111 |
+ |
.I bsdfview |
| 112 |
+ |
with the |
| 113 |
+ |
.I "-v 0" |
| 114 |
+ |
option. |
| 115 |
+ |
.PP |
| 116 |
+ |
If an optional plotting range is given with the |
| 117 |
+ |
.I \-r |
| 118 |
+ |
option, this will override automatic settings from the BSDF input. |
| 119 |
+ |
This may be useful for comparing different BSDF sources. |
