yes it works! ((-:
thank you very much!

btw: is there a list like "recommended readings" for people who are starting
to learn radiance? I would like to know, as an example, what kind of math
and physics people (really) have to know, and which books are recommended
therefor etc.
I have orderd the "The Art And Science Of Lighting Visualization" - is
everything (and more...) I (will) ask about inside this book?

all the best

just have a morning chat with the main brad guru:
Francesco itself ;-)))
we tried different things and we think to have identified the problem:

-1- make sure that ximage works at all on your system (just a silly check,
but you never know)
-2- if ximage works, the solution is then to start blender from the
terminal.

to do that you need to go into:
blender.app/contents/macos

in fact blender.app is a folder folder as all macosx applications
(to browse it you need to ctlr+click on it and ask for 'show contents' in
the contextual menu)

when you are into
blender.app/contents/macos
just type:
./blender

the GUI starts and everything works.
plus you are able to see error messages in the terminal window (good if you
need to fix a problem)
only small problem is that the window is larger than the screen, but you can
adjust the menu position by dragging them.

hope it works now
cheers

Hello everyone! I'm really new to radiance and first I have to say:

Thank You Very Much For Developing And Supporting This Free Software!!

Radiance is running fine on my system (far as i can see) with macos 10.3.7,
blender 2.3.6, python 2.3.

My question is more about blender and brad because

everything seems to work in general, but if i try the sky preview
i get the following in the console window:

" ximage
/Applications/Blender/blender.app/Contents/MacOS/.blender/scripts/brad/tmp/
mph.pic: cannot open display"

I've edited my bash_profile like it was explained from pillo:

--------
if someone is interested in using x11 as graphical output for the built
in panther terminal this is what is required:

1) launch x11, launch terminal (keep X11 always open when the terminal
is open, otherwise it doesn't work!)

2) edit your .bash_profile as follows, just add these lines:

if [ -z "${DISPLAY}" ];then echo -n
export DISPLAY=':0'
fi
---------

but sadley it has not the desired (display-) effect to applications
controlled via brad/blender, too.

would it be possible to open x-window-radiance-applications like ximage out
of blender/python in a way that they use x-darwin and its display?

thank you very much and all the best

johannes
