.SH DESCRIPTION
.I Objview
renders a RADIANCE object interactively using
.I rad(1)
or
.I glrad(1).
This program is merely a shell script that adds some light
sources to a scene then calls
.I rad(1)
or
.I glrad(1)
to make an octree and view the scene interactively.
.PP
If the default up vector (+Z) is inappropriate
for this object, then specify a different one using the
.I \-u
option to
.I objview.
.PP
Any number of material and scene files may be given,
but no in-line commands or standard input.
.PP
There is also a Ruby version of objview (objview.rb)
available, primarily for Windows compatibility, but 
the Ruby version also adds a luminaire viewer option.
.PP 
If the user specifies the -l option, then a Radiance 
luminaire description is the input to the program. 
objview.rb will place the centroid of the luminiare at 0,0,0
and surround the distribution with a room that is 4' square
(in meters), with a view along the positive y. Scale the
room size with the -r option.
.PP
The number of processors to use may be specified with the 
-n option.
