directions are related to some set of measured values, such as an array of |
| 36 |
|
illuminance points or images. |
| 37 |
|
This matrix is usually computed by |
| 38 |
< |
.I rtcontrib(1) |

.I rcontrib(1) |
| 39 |
|
for a particular set of windows or skylight openings. |

|
The second argument is the window transmission matrix, or BSDF, given as |
| 41 |
|
a standard XML description. |
| 44 |
|
This is usually computed using |
| 45 |
|
.I genklemsamp(1) |
| 46 |
|
with |
| 47 |
< |
.I rtcontrib |
| 47 |
> |
.I rcontrib |
| 48 |
|
in a separate run for each window or skylight orientation. |
| 49 |
|
The final input is the sky contribution vector, |
| 50 |
|
usually computed by |
