secondary sources whose contributions can be computed more efficiently by |
| 21 |
|
.I rpict(1) |
| 22 |
|
and |

|
This type of optimization is most useful for windows and skylights which |
| 25 |
|
represent concentrated sources of indirect illumination. |
| 26 |
|
.I Mkillum |
| 29 |
|
These are best handled respectively by the ambient calculation |
| 30 |
|
and the secondary source types in RADIANCE. |

than there are local CPUs available to do the work. |
