[Radiance-general] Exporting file from Ecotect to Radiance

[Krystyna Zelenay]

I would like to thank everyone for their advice. It looks like the problem
has been resolved and that it was not related to the fact that the rview.exe
application does not come with the version of Radiance I am using (MinGW
Radiance Installer for Windows (HEAD snapshot 2008-04-17) available for
download at http://www.radiance-online.org/).

 I had to reset my Radiance directory within the 'image viewer' program in
order to be able to apply any of the overlays. Below is an excerpt from an
NRC document explaining how to get started with Ecotect-Radiance-DAYSIM
(available at http://irc.nrc-cnrc.gc.ca/ie/lighting/daylight/daysim_e.html),
in which specific reference is made to the issue I experienced:

 Please note: The first time you are trying to generate a falsecolor image
you might get an error message stating "RGBE read error". If this is the
case, you have to reset your Radiance directory within the 'image viewer'
program above under OPTIONS >> SETTINGS (see also Step 30.a).

 The NRC document describes how to import/export files from
Ecotect/Radiance/DAYSIM. It is very helpful, although parts of it may be
slightly outdated.  For example, I think that the link provided for the
Radiance download (
http://www.arch.mcgill.ca/prof/reinhart/software/Radiance3P7forWindows.zip)
may refer to an older version of Radiance.

 I am keeping my fingers crossed things will run smoothly from now on!

old, but if it is still available, it will resolve these issues.  Their
instructions--I hope they still work--are here: <

more current Radiance, try copying "rvu" to "rview"; it is unlikely that you
have "vi" on your Windows system to create a name conflict.

problem? If so, what are alternative ways for evaluating the radiance image?
