.SH DESCRIPTION |
| 35 |
.I Objview |
| 36 |
renders a RADIANCE object interactively using |
| 37 |
.I rad(1) |
| 38 |
or |
| 39 |
.I glrad(1). |
| 40 |
This program is merely a shell script that adds some light |
| 41 |
sources to a scene then calls |
| 42 |
.I rad(1) |
| 43 |
or |
| 44 |
.I glrad(1) |
| 45 |
to make an octree and view the scene interactively. |
| 46 |
.PP |
| 47 |
If the default up vector (+Z) is inappropriate |
| 48 |
for this object, then specify a different one using the |
| 49 |
.I \-u |
| 50 |
option to |
| 51 |
.I objview. |
| 52 |
.PP |
| 53 |
Any number of material and scene files may be given, |
| 54 |
but no in-line commands or standard input. |
| 55 |
.PP |
| 56 |
There is also a Ruby version of objview (objview.rb) |
| 57 |
available, primarily for Windows compatibility, but |
| 58 |
the Ruby version also adds a luminaire viewer option. |
| 59 |
.PP |
| 60 |
If the user specifies the -l option, then a Radiance |
| 61 |
luminaire description is the input to the program. |
| 62 |
objview.rb will place the centroid of the luminiare at 0,0,0 |
| 63 |
and surround the distribution with a room that is 4' square |
| 64 |
(in meters), with a view along the positive y. Scale the |
| 65 |
room size with the -r option. |
| 66 |
.PP |
| 67 |
The number of processors to use may be specified with the |
| 68 |
-n option. |
