Radiance-general Digest, Vol 159, Issue 12

Hi Everyone:
Thanks for the tips; much appreciated.

When I type in echo $RAYPATH, it returns ".:/usr/local/radiance/lib"
When I type in echo $PATH, it returns "
/usr/local/radiance/bin:/usr/local/radiance/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin"

picture.cal is entered properly in the .rad file (no directory paths in
front of the command)

Hello Everyone: I learned a little unix to be able to work with Radiance
(for some upcoming projects that require me to reconstruct very specific
lighting conditions), but I am running into some problems:

I followed the instructions for installing Radiance on Mac OSx (10.11.6)

created a file ~/.bashrc with the following arguments:
export PATH=/usr/local/radiance/bin:$PATH
export RAYPATH=.:/usr/local/radiance/lib

I followed Greg W's Radiance Ch. 1 tutorial and successfully modeled a
sphere on a pedestal and in a room (exciting).

However, when I tried to do more sophisticated work (the Image Mapping
tutorials by Axel Jacobs in the Radiance Cookbook), I received an error
that "picture.cal" does not exist.

I ran "ls -la /usr/local/radiance/lib" and noticed that picture.cal was
missing. After poking around, I discovered another path to /radiance/lib
and then ran "ls -la /opt/rad4/radiance-5.0.a.12-
Darwin/usr/local/radiance/lib"
and found picture.cal as well as many other files not in the original
directory path above. I copied picture.cal into the directory for the
RAYPATH, but still received the error.

Anyway, I tried re-setting RAYPATH to
"/opt/rad4/radiance-5.0.a.12-Darwin/usr/local/radiance/lib"
(as well as =.:/opt/rad4/radiance-5.0.a.12-Darwin/usr/local/radiance/lib)
but I still received an error that picture.cal was missing. I finally
figured out a very kludgy way to get the missing files in radiance/lib to
work (by copying them into the current working directory), but I want to
get the RAYPATH working properly.

Does anyone have advice/help?

Thank you very much, David

Hi David,

It's difficult to say for certain, but you should know that altering your
.bashrc file only affects the next open Terminal window. It doesn't change
the RAYPATH setting in the shell you already have running.

You should open a new Terminal window and enter "echo $RAYPATH" to make
sure your environment setting is in effect. If it is, and you can read the
associated directory, then something else must be wrong.

Cheers,
-Greg

Check that picture.cal is indeed used as "picture.cal" and not as
"./picture.cal". The leading "./" will only search in the current scene
directory and ignore the RAYPATH settings.

You can also type

    source ./bashrc

in the terminal to reread the configuration and apply any changes you made
to the current bash session.

*************************************************

Sorry this is giving you so much trouble. I still remember the excitement
I felt when I saw the Tutorial 0 scene appear in my rvu window the first
time!

What *nix are you using, and which version of the Radiance installer did
you use? Also, did you follow the advice and either a) try the commands in
a new terminal window after making the changes to your ~/.bashrc, or, b)
type 'source ~/.bashrc’ in the current terminal window?

Check that picture.cal is indeed used as "picture.cal" and not as
"./picture.cal". The leading "./" will only search in the current scene

Check that picture.cal is indeed used as "picture.cal" and not as
"./picture.cal". The leading "./" will only search in the current scene
directory and ignore the RAYPATH settings.

You can also type

   source ./bashrc

in the terminal to reread the configuration and apply any changes you
made to the current bash session.

Hello Everyone: I learned a little unix to be able to work with Radiance
(for some upcoming projects that require me to reconstruct very specific
lighting conditions), but I am running into some problems:

I followed the instructions for installing Radiance on Mac OSx (10.11.6)

created a file ~/.bashrc with the following arguments:
export PATH=/usr/local/radiance/bin:$PATH
export RAYPATH=.:/usr/local/radiance/lib

I followed Greg W's Radiance Ch. 1 tutorial and successfully modeled a
sphere on a pedestal and in a room (exciting).

However, when I tried to do more sophisticated work (the Image Mapping
tutorials by Axel Jacobs in the Radiance Cookbook), I received an error
that "picture.cal" does not exist.

I ran "ls -la /usr/local/radiance/lib" and noticed that picture.cal was
missing. After poking around, I discovered another path to /radiance/lib
and then ran "ls -la
/opt/rad4/radiance-5.0.a.12-Darwin/usr/local/radiance/lib" and found
picture.cal as well
as many other files not in the original directory path above. I copied
picture.cal into the directory for the RAYPATH, but still received the
error.

Anyway, I tried re-setting RAYPATH to
"/opt/rad4/radiance-5.0.a.12-Darwin/usr/local/radiance/lib" (as well as
=.:/opt/rad4/radiance-5.0.a.12-Darwin/usr/local/radiance/lib) but I still
received an error that picture.cal was missing. I finally
figured out a very kludgy way to get the missing files in radiance/lib
to work (by copying them into the current working directory), but I want
to get the RAYPATH working properly.

Does anyone have advice/help?

Thank you very much, David
