If the letter 't' appears in |
| 115 |
|
.I spec, |
| 116 |
|
then the fields following will be printed for every ray traced, |
| 118 |
|
If the capital letter 'T' is given instead of 't', then all rays will |
| 119 |
|
be reported, including shadow testing rays to light sources. |
| 120 |
|
Spawned rays are indented one tab for each level. |
| 121 |

The tilde marker ('~') is a handy way of differentiating the final ray |
| 122 |
+ |
value from daughter values in a traced ray tree, and usually appears |
| 123 |
+ |
right before the 't' or 'T' output flags. |
| 124 |
+ |
E.g., |
| 125 |
+ |
.I \-ov~TmW |
| 126 |
+ |
will emit a tilde followed by a tab at the end of each trace, |
| 127 |
+ |
which can be easily distinguished even in binary output. |

The program can use either an include list or an exclude |

list, but not both. |
