Using raw float or double records for example can reduce the time |
| 37 |
|
requirements of transferring and interpreting information in |
| 38 |
|
.I rtrace. |

The |
| 41 |
+ |
.I \-c |
| 42 |
+ |
option repeats each pixel the given number of times (default is 1). |
| 43 |
+ |
This is most useful when sending rays to |
| 44 |
+ |
.I rtcontrib(1) |
| 45 |
+ |
with the same |
| 46 |
+ |
.I \-c |
| 47 |
+ |
setting, providing a much faster way to average pixels over image sets. |
| 48 |
+ |
The |
| 49 |
+ |
.I \-pj |
| 50 |
+ |
option should be used to jitter sample postions in most cases. |
