.SH DESCRIPTION
|
| 18 |
|
|
.I Lookamb
|
| 19 |
|
|
examines an ambient file produced by
|
| 20 |
|
|
.I rpict(1),
|
| 21 |
|
|
.I rtrace(1),
|
| 22 |
|
|
or
|
| 23 |
greg |
1.3 |
.I rvu(1).
|

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.
