.SH DESCRIPTION
|
| 14 |
.I Ra_bmp
|
| 15 |
converts each input map to a suitable visualization as a BMP image.
|
| 16 |
Supported types include Radiance pictures, depth maps produced by
|
| 17 |
.I rcode_depth(1),
|
| 18 |
identifier maps from
|
| 19 |
.I rcode_ident(1),
|
| 20 |
and surface normal maps from
|
| 21 |
.I rcode_norm(1).
|
| 22 |
Each input file is identified by the FORMAT string it its header,
|
| 23 |
and if it belongs to one of the supported types, a new file with the
|
| 24 |
same name will be created with its suffix replaced by ".bmp".
|
| 25 |
If a previous BMP file exists with the same name, it will be overwritten.
|
| 26 |
.PP
|
| 27 |
Radiance pictures are tone-mapped as if calling:
|
| 28 |
.IP "" .2i
|
| 29 |
ra_bmp -e auto file.hdr file.bmp
|
| 30 |
.PP
|
| 31 |
If the
|
| 32 |
.I \-x
|
| 33 |
and
|
| 34 |
.I \-y
|
| 35 |
options are given, these will be used as the maximum output image dimensions,
|
| 36 |
and this holds for all input types.
|
| 37 |
.PP
|
| 38 |
Depth maps from
|
| 39 |
.I rcode_depth
|
| 40 |
are processed using
|
| 41 |
.I falsecolor(1)
|
| 42 |
with an appropriate scale and label.
|
| 43 |
.PP
|
| 44 |
Identifier maps from
|
| 45 |
.I rcode_ident
|
| 46 |
are assigned a random color for each identifier.
|
| 47 |
.PP
|
| 48 |
Surface normal maps are processed using an HSV (hue, saturation, value)
|
| 49 |
color space that assigns normal orientation
|
| 50 |
to a hue angle, and saturation runs from 0 when the normal is aligned to
|
| 51 |
the view origin, to maximum saturation at tangential edges.
|
| 52 |
Back-facing normals will be darker -- a normal in the direction opposite
|
| 53 |
to the viewer being pure black.
