takes a single XML file representing a Klems or tensor tree BSDF, plotting |
| 30 |
|
as many scattering hemispheres as are present in the file. |

|
In the second form, |
| 32 |
|
.I bsdf2rad |
| 76 |
|
Positive phi is read counter-clockwise from above, |
| 77 |
|
and a phi of 90 degrees (+Y) typically corresponds |
| 78 |
|
to a material's "up" orientation. |

.PP |
| 80 |
+ |
If an optional plotting range is given with the |
| 81 |
+ |
.I \-r |
| 82 |
+ |
option, this will override automatic settings from the BSDF input. |
| 83 |
+ |
This may be useful for comparing different BSDF sources. |
