.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 |

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. |
