[Radiance-general] Where does bgraph look for .plt files?

[Greg Ward]

That is very strange in that case.  What happens when you run the following:

	csh -f -c 'ls -l ${MDIR}line.plt'

You should see something like:

	-rw-r--r--  1 gward  admin  728 Feb 13  1990   /usr/share/radiance/meta/line.plt

...only with your user name, obviously.  Make sure the file is readable.  The contents of the file should be:

#
#	This file defines a standard line plot,
#	where a curve is represented by lines
#	connecting each point.
#

include = standard.plt		# standard definitions

lthick = 2	# line thickness

(...and so on...)

I can't think what else might be wrong.

I just crosschecked again. May be there is something not working on my system. Or not a good day today. Thank you!

Some default directory location gets compiled in, but it must not agree with your particular installation location.  This variable is separate from the $RAYPATH setting, but similar.  It is the only other variable you need set in Radiance, as these plotting tools predate any of the others.
