x11meta issue

radiance-general
1

Hi I am having issues with the x11meta command.
If I run

objline objects/things.rad | x11meta (from Alex's tutorial), I keep
receiving the error:

xform: cannot find file "things.rad"
fatal - cannot open file "/usr/local/lib/meta/vchars.mta", mode "r"
xform: cannot find file "things.orig"

- I am on Mac OSX Yosemite.
- Last 5.0 binaries installed in default directory
- PATH, RAYPATH set correctly
- x11 installed from xQuarz.org

I have checked other threads and it seems other people had the same issue,
but no solution was provided.

Any suggestion?

Thanks
Ruggiero

Make sure you are in the right directory, or pointing to the right directory. -Chris

Chris’ directory/path advice will fix errors one and three in your output
below, but error two is unfortunately a result of the NREL binary packages
not working correctly for x11meta. Sorry about that, I haven’t had a chance
to sort that one out yet. Used to be, no one ever used x11meta but it
appears lots of people are starting to pick up Axel’s tutorial which
includes the use of that tool, so I guess I’d better get this sorted!

I don't know why xform is complaining, but the problem with x11meta *may* be the MDIR environment variable, which should point to the appropriate library directory on your system. Mine is set to the location of:

  $MDIR=/usr/local/lib/ray/meta/
  export MDIR

Note the trailing '/' which is very important. Generally speaking, this directory sits in a "meta" subdirectory of the main Radiance library.

Hope this helps!

Thanks Greg,

This vchars.mta file, is this a Radiance thing, or a system thing? The only references I see to this filename in all the Radiance source are in pexpand.c and expand.c:

I do not see the file itself. I ASSumed this was because my installers weren’t packaging it, but it doesn’t seem to be in the Radiance repo at all, at least not in the mirror. On my entire storage device, I only see this file in a couple of places, and they’re all locations where I had really old archived installations of Radiance (built with your “makeall” script). This makes me think this is a Radiance thing that somehow never got included in the mirror...

Hmmm.... Unlike other "essential" library files, the meta/ folder is only distributed as part of the supplementary material in the "rad5R0all.tar.gz" ball at:

  http://www.radiance-online.org/download-install/radiance-source-code/latest-release

It lives in the ray/lib/meta/ subfolder of this distribution. We could think about creating a subdirectory in the ray/src/meta directory and having it install from there if that makes more sense. We should probably take this offline, or move it to the "dev" list.

@Ruggiero - try getting the above distribution and extracting the meta directory onto your system, setting the MDIR environment variable appropriately. Hopefully, that will fix the issue for you. We'll work on this for the next package, I guess.

Cheers,
-Greg

Thanks Greg and Rob

I added the "meta" folder from the source distribution in ray/lib/meta/ and
the problem with x11meta is gone and I can now see the output in X11. My
original installation is still in /usr/local/radiance/.

Still having one of the problems with xform though and not sure why

I am working from the folder

~/dev/radiance

I create the file things.rad in ~/dev/radiance/objects

and then I use "objline ./objects/things.rad | x11meta"

The use of "./" has solved the issue of objline not finding things.rad, but
it still complains about the file things.orig. Do i need to create this
file or it is just a warning?

Thanks
Ruggiero

Hi Ruggiero,

Do you have dot (".") in your RAYPATH? If not, then xform won't look in your current directory(!) for named input files. I would add "." to the beginning of RAYPATH if it isn't there already.

I don't know why you wouldn't be getting an oblique view from objline. It seems to generate all 4 views when I run it.

That was the problem. Everything working as expected now and I can also see
the oblique view.

take this offline, or move it to the "dev" list.

@Ruggiero - try getting the above distribution and extracting the meta
directory onto your system, setting the MDIR environment variable
appropriately. Hopefully, that will fix the issue for you. We'll work on
this for the next package, I guess.

Cheers,
-Greg

Thanks Greg,

This vchars.mta file, is this a Radiance thing, or a system thing? The
only references I see to this filename in all the Radiance source are in
pexpand.c and expand.c:

https://github.com/NREL/Radiance/search?utf8=✓&q=vchars.mta

I do not see the file itself. I ASSumed this was because my installers
weren’t packaging it, but it doesn’t seem to be in the Radiance repo at
all, at least not in the mirror. On my entire storage device, I only see
this file in a couple of places, and they’re all locations where I had
really old archived installations of Radiance (built with your “makeall”
script). This makes me think this is a Radiance thing that somehow never
got included in the mirror...

I don't know why xform is complaining, but the problem with x11meta *may*
be the MDIR environment variable, which should point to the appropriate
library directory on your system. Mine is set to the location of:

$MDIR=/usr/local/lib/ray/meta/
export MDIR

Note the trailing '/' which is very important. Generally speaking, this
directory sits in a "meta" subdirectory of the main Radiance library.

Hope this helps!

Chris’ directory/path advice will fix errors one and three in your output
below, but error two is unfortunately a result of the NREL binary packages
not working correctly for x11meta. Sorry about that, I haven’t had a chance
to sort that one out yet. Used to be, no one ever used x11meta but it
appears lots of people are starting to pick up Axel’s tutorial which
includes the use of that tool, so I guess I’d better get this sorted!

Make sure you are in the right directory, or pointing to the right
directory. -Chris

Hi I am having issues with the x11meta command.
If I run

objline objects/things.rad | x11meta (from Alex's tutorial), I keep
receiving the error:

xform: cannot find file "things.rad"
fatal - cannot open file "/usr/local/lib/meta/vchars.mta", mode "r"
xform: cannot find file "things.orig"

- I am on Mac OSX Yosemite.
- Last 5.0 binaries installed in default directory
- PATH, RAYPATH set correctly
- x11 installed from xQuarz.org

I have checked other threads and it seems other people had the same
issue, but no solution was provided.

Any suggestion?

Thanks
Ruggiero
