.SH DESCRIPTION |
| 18 |
.I Lookamb |
| 19 |
examines an ambient file produced by |
| 20 |
.I rpict(1), |
| 21 |
.I rtrace(1), |
| 22 |
or |
| 23 |
.I rvu(1). |
| 24 |
The default mode prints the position, direction, level, weight, |
| 25 |
radius, value, position gradient and direction gradient |
| 26 |
for each stored ambient value preceded by a |
| 27 |
label appropriate for human interpretation. |
| 28 |
The |
| 29 |
.I \-d |
| 30 |
option prints the same quantities in 18 columns without any expanatory |
| 31 |
text, and is more appropriate as input to another program. |
| 32 |
.PP |
| 33 |
The |
| 34 |
.I \-r |
| 35 |
option performs the reverse conversion, taking the output of lookamb |
| 36 |
and reproducing the original ambient file on the standard output. |
| 37 |
.PP |
| 38 |
The |
| 39 |
.I \-h |
| 40 |
option causes lookamb not to print out the header information on the |
| 41 |
output, or not to expect it on the input with the |
| 42 |
.I \-r |
| 43 |
option. |
| 44 |
.PP |
| 45 |
If no file is given, |
| 46 |
.I lookamb |
| 47 |
reads from the standard input. |
| 48 |
.SH NOTES |
| 49 |
Before release 2.2 of Radiance, ambient files were in a |
| 50 |
machine-dependent format. |
| 51 |
Since that is no longer the case, ambient files can now be moved |
| 52 |
freely between machines without any conversions. |
| 53 |
Thus, the only reason to use |
| 54 |
.I lookamb |
| 55 |
now is to examine the contents of an ambient file. |
