takes one or more XML files, each describing the bidirectional scattering |
| 16 |
|
distribution function of a surface or geometric system, and packages |
| 17 |
|
them into RADIANCE scene descriptions. |

If the input file(s) do not begin with a '.' or '/', the directories |

in the RAYPATH environment variable will be searched. |

|
One rectangle is produced for each BSDF that has |
| 21 |
|
no detail geometry and/or no rear-side reflectance distribution. |
| 22 |
|
If both front and back reflectance distributions are present with |
| 23 |
|
detail geometry, then two rectangles will be used to sandwich |
| 24 |
|
the geometry extracted from the BSDF file. |
| 25 |
+ |
The front surface will always be centered just in front of the |
| 26 |
+ |
origin facing the positive Z-direction, with "up" in the positive |
| 27 |
+ |
Y-direction. |
| 28 |
+ |
The back surface, if present, will parallel the front surface at |
| 29 |
+ |
a distance slightly greater than the BSDF system thickness. |
| 30 |
+ |
Scene units will always be in meters. |
