Radiance-general Digest, Vol 60, Issue 9

Hi all,

I have fixed this same problem, instaling the old Desktop Radiance and
copyng from it the *rview.exe* and *winimage.exe* files to my new radiance
3.9 binaries folder. It works very fine.

Take care to install radiance in a folder with a name without spaces, it´s
sound silly but it´s important!

(eg: c:/radiance)

Hi,

I have just uninstalled Desktop Radiance and installed the MinGW version on
my computer (Windows OS). I have been informed that this is the latest
version of Radiance for Windows OS. Unfortunately I now have trouble
reading
images exported from Ecotect.

When I export the Ecotect example file "RADIANCE_example.eco" I am able to
see a rendered view of the space in the image viewer, but I cannot run any
of the options for the information overlay (e.g. contour lines, false
color,
daylight factors etc.) and get the message "RGBE read error"
When exporting the file from Ecotect, I noticed that when checking whether
Radiance is functional, the exporter returned a message saying that the
application "rview" is missing from the directory. Could this be the
problem? If so, what are alternative ways for evaluating the radiance
image?

I have uploaded an image of the error message to the Autodesk discussion
forum:

Thanks,

Krystyna

Hi,

the subject-line of this mail is not very helpful. What kind of file do
you want to export from Ecotect? I try to understand what you wrote, and
it seams that you want to use the image processing tools of Radiance on
images generated in Ecotect, is this the case? I also do not know which
"image viewer" you refer to, the only image viewer in Radiance that I am
aware of is ximage, and it offers no such things like your information
overlay functionality, as this is done by filters in Radiance. So I
guess you are using other software here, not Radiance.

Can you please find out some details about what kind of data you want to
process using which Radiance tools?

Good luck, Lars.

Unfortunately 'falsecolor' (which is the master tool behind most
of these overlays) is not distributed with the MinGW binaries
because it is a CSH-script that does not run on Windows. Therefore
the ImageViewer bundled with Ecotect can not generate this type
of analysis.

There is another picture viewer around which is based on
Python and that seems to be the best option to create
falsecolor images on Windows at the moment:

Raddisplay - http://www.deluminaelab.com/en/tools.html

It requires some time to setup, though.

The application 'rview' is now called 'rvu' and AFAIK it has
not been ported to Windows.

There have been some significant changes to the Radiance
applications since Desktop Radiance has been released. This
affects mostly the rendering process, though. The image format
is still the same and you should be able to open a 'new'
image in the old 'rview'. You could try to copy the missing
applications from your DR installation over to the MinGW
installation and see if that solves your problem.

Regards,
Thomas
