.SH NOTES |
| 113 |
– |
Users should seriously consider using |
| 114 |
– |
.I rpiece(1) |
| 115 |
– |
for multiprocessing |
| 116 |
– |
when irradiance caching is employed with a shared ambient file. |
| 117 |
– |
If |
| 118 |
– |
.I rtpict |
| 119 |
– |
is used with |
| 120 |
– |
.I \-n |
| 121 |
– |
greater than 1, it tries to compute neighboring parts |
| 122 |
– |
of the same scanline in different processes, which can |
| 123 |
– |
result in many redundant calculations and cache entries. |
| 124 |
– |
.I Rtpict |
| 125 |
– |
will automatically run a randomly-ordered overture calculation |
| 126 |
– |
to mitigate this problem, but it is not a perfect solution. |
| 127 |
– |
.I Rpiece |
| 128 |
– |
avoids redundant cache calculations by working on separate tiles in each |
| 129 |
– |
process, which brings other benefits as well, such as enabling the |
| 130 |
– |
.I \-ps |
| 131 |
– |
option for image plane sampling. |
