Thanks Lars and Thomas,
It is working !!
I copied the rayinit.cal and skybright.cal into project folder. Now "rpict: command is working. Image is rendered and i am able to see in HDR shop.
Definitively a PATH problem, then.
Well i am not a expert unix guy.... just started with cygwin.....
Be told that you will suffer more than necessary for using cygwin. If you have the resources I recommend installing Linux on an old computer or setting up a virtual machine with Linux. It will make it easier for you to understand Unix.
Now i really want to fix the problem of PATH for future. Therefore i am explaining my directory structure.
Under cygwin\home\abc directory ..... i have folder "opt" and files .bashrc , .inputrc, bash_profile, BASH_HISTORY
First: According to this you are user 'abc' on your Windows machine. Is this correct or did you set this up intentionally? You can verify by typing
in the console window. The first should give you 'abc' the second '/home/abc'
Second: This 'opt' is not were it is intended to be. That might be the problem.
Cygwin creates its own file system 'root' in its installation directory (typically "C:\cygwin"). Every command you enter in a Cygwin shell will use this as the start for the file system tree. An absolute file path in Unix starts with '/' (no dot!). So if you see a Unix path '/home/abc' this translates to "C:\cygwin\home\abc".
Following this logic '/opt/radiance/cygwin-radiance_dist-3R9/bin' should be found as
"C:\cygwin\opt\radiance\cygwin-radiance_dist-3R9\bin". Just keep the files as they are and move the cygwin-radiance_dist-3R9 folder to the right location.
You should not mix your project files with files in the distribution. You might accidentally destroy essential files.
bash_profile changed content is given below
Note that there should be a '.' in front of the file name: '.bash_profile'. The '.' hides the name for the user so this file is somewhat protected. It is still part of the file name and without it the file will not be recognised. This may be why you don't have the $RAYPATH set correctly.
# System-wide .bashrc file
# change the directories if necessary
export PATH RAYPATH MANPATH
If you follow the renaming as above these settings should work now.
then under cygwin\home\abc\opt\radiance\cygwin-radiance_dist-3R9
i have "bin", "doc", "lib" and "obj" folders. and my source files ( now it includes rayinit.cal and skybright.cal) are also into - "cygwin\home\abc\opt\radiance\cygwin-radiance_dist-3R9"
Move your source files to a folder in your HOME directory ('/home/abc/project1' for example). Keep your Radiance installation clear!
When i relaunch the cygwin console and execute $PATH .... i get the following info on the console
bash: usr/local/bin: /usr/bin: /bin : /usr/X11R6/bin : /cygdrive/c/Program: No such file or directory.
and when i do $RAYPATH then no message or info comes on the console.
See above. IF you are user 'abc' AND the file is called '.bash_profile' it should work.
for execution of source file - once i am inside the "cygwin\home\abc\opt\radiance\cygwin-radiance_dist-3R9" ditectory
1. export PATH=$HOME/opt/radiance/cygwin-radiance_dist-3R9/bin/:$PATH
What you do here is what should happen in the config file. You only did change the PATH setting, but did not create a RAYPATH. Therefore you could use oconv and rpict but the search for 'rayinit.cal' failed.
One last thing: If you copy-and-past from Windows to Linux you should change the line end characters. Windows will create a '\r\n' at the end of a text file while Unix only uses '\n'. The bash configuration files should not be affected, but other programs might have problems with that.
