.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.
