Dear list,
this might be of interest to rad-openstudio, but I am refraining from
cross-posting.
Whilst doing a bit of Radiance teaching last Friday, I got caught
red-face in my attempt to use objview.rb. Installing ruby.zip from the
NREL web site (and making sure %PATH% picks it up) did not
help--objview.rb kept complaining about missing input files. It appears
that somehow, ARGV is completely ignored by the parser once the options
are dealt with. However, I know little about Ruby.
Since I need a working objview next Friday, I finished the re-write of
objview in Perl, which I started some time ago, but never polished off.
Whilst at it, I also completed a Perl port of objpict.csh.
Both appear to work under LINUX and Windows Vista. Zip archive with
Windows exe files is here:

Your feedback would be much appreciated.
Since the Windows objview.rb has some extra functionality over the UNIX
csh version (namely ltview), I started work on a x-plat ltview.pl, but
have I admit that I'm not sure what it is meant to do:
a) if ltview is meant to show the actual luminaire (or fixture for you
non-Europeans), then are not objview or objpict good enough?
b) if, on the other hand, it is the actual photometric distribution that
matters, then would it not be better to extract the dat file of the
distribution, and suspend a little disk or square with that distribution
applied to it. The command line parser could then be extended to
- include an option that might cause it to put the disk inside a sphere
rather than a box; and/or
- render a -vta fisheye view from just below this disk, so that the
entire photometric distribution might be appreciated.
I'm happy enough to look into this if it is felt that the Windows
version of objview and the 'official' one should be based on the same
code. Would need some guidance, though as to what ltview should do.
Good night and good luck
Axel
PS: I'd love to call it 'iesview', but this name is already taken by an
add-on to AGI32. Works pretty well, actually (under Windows).
@Ian, we probably have to thank you for this little gem?
