.BR PICTURE |
| 372 |
|
This is the root name of the output picture file(s). |
| 373 |
|
This name will have appended the view identifier (or a number if no |
| 374 |
< |
id was used) and a ".pic" suffix. |
| 374 |
> |
id was used) and a ".hdr" suffix. |
| 375 |
|
If a picture corresponding to a specific view exists and is not out |
| 376 |
|
of date with respect to the given octree, it will not be |
| 377 |
|
re-rendered. |
| 439 |
|
few places, it should be set to HIGH. |
| 440 |
|
The default value is "L". |

.BR PGMAP |
| 443 |
+ |
This variable designates a global photon map to be generated by |
| 444 |
+ |
.I mkpmap(1) |
| 445 |
+ |
and used to accelerate rendering. |
| 446 |
+ |
The file name must be followed by the number of photons to be stored |
| 447 |
+ |
in the map, and this number may be followed by a bandwidth for rendering. |
| 448 |
+ |
There is no default value, meaning that a global photon map will not |
| 449 |
+ |
normally be created. |

.BR PCMAP |
| 452 |
+ |
This variable designates a caustic photon map to be generated by |
| 453 |
+ |
.I mkpmap(1) |
| 454 |
+ |
and used during renderings to model light transmission by reflecting |
| 455 |
+ |
and refracting surfaces. |
| 456 |
+ |
The file name must be followed by the number of photons to be stored |
| 457 |
+ |
in the map, and this number may be followed by a bandwidth for rendering. |

There is no default value, meaning that a caustic photon map will not |

.SH BUGS |
| 675 |
+ |
You cannot run more than one |
| 676 |
+ |
.I rad |
| 677 |
+ |
process at a time on the same input file, |
| 678 |
+ |
as the second process will attempt to recover the output files |
| 679 |
+ |
of the first process, damaging the results. |
| 680 |
+ |
The exceptions to this are running interactively via the |
| 681 |
+ |
.I \-o |
| 682 |
+ |
option, or rendering different views using the |
| 683 |
+ |
.I \-v |
| 684 |
+ |
option. |
| 685 |
+ |
.PP |
| 686 |
|
Incremental building of octrees is not supported as it would add |
| 687 |
|
considerable complexity to |
| 688 |
|
.I rad. |
| 719 |
|
The use of upper and lower case naming for the standard views may be |
| 720 |
|
problematic on systems that don't distinguish case in filenames. |
