.SH EXAMPLES |
| 105 |
|
To render a scene with four processes: |
| 106 |
|
.IP "" .2i |
| 109 |
|
To render radiance, first surface distance, and normals in a layered image: |
| 110 |
|
.IP "" .2i |
| 111 |
|
rtpict -n 8 -vf fish.vf @render.opt -ovLn fisholay scene.oct |

.SH NOTES |
| 113 |
– |
Users should seriously consider using |
| 114 |
– |
.I rpiece(1) |
| 115 |
– |
when irradiance caching is employed with a shared ambient file. |
| 116 |
– |
If |
| 117 |
– |
.I rtpict |
| 118 |
– |
is used in multiprocessing mode with a shared irradiance cache, |
| 119 |
– |
it is trying to compute almost |
| 120 |
– |
the same part of the same scanline in different processes, which |
| 121 |
– |
results in many redundant calculations. |
| 122 |
– |
The |
| 123 |
– |
.I rpiece |
| 124 |
– |
program avoids this by working on separate tiles in each |
| 125 |
– |
process, with less overlap in the indirect irradiance calculation. |
| 126 |
– |
Either program will benefit from an "overture" run of a |
| 127 |
– |
single-process rpict to create the ambient file using a low-resolution |
| 128 |
– |
rendering that is discarded, but this will not completely solve the |
| 129 |
– |
problem for |
| 130 |
– |
.I rtpict. |
