This is mesa bug https://bugs.freedesktop.org/show_bug.cgi?id=16866. If you build the GLX plugin (set K3D_BUILD_GLX_MODULE to ON in CMake) you should get a warning that your Mesa version is too old. I recommend upgrading to 7.6 or later, although this particular bug has been fixed starting with 7.5.1.
I should probably move the mesa version check to the opengl module, since it only uses pure OpenGL functions.
Actually, K3D_BUILD_GLX_MODULE is ON by default on FreeBSD (UNIX AND NOT APPLE) ... the problem seems to be that glGetString(GL_VENDOR) returns "Mesa Project" which is what I would expect. The source code in mesa_version_check.cpp is testing for "Tungsten Graphics, Inc", about which I'm highly skeptical ;)
Cheers,
Tim
Actually, it looks like "Tungsten Graphics, Inc" is the vendor for recent versions of Mesa, and "Mesa Project" is the vendor for older versions. So it appears that we should be testing for both; however, even with that change the test doesn't work on my FreeBSD VM; it appears that glewGetContext() fails; this points to a longstanding issue where we need to cleanup our initialization of OpenGL.
Cheers,
Tim

By the way, this may not help, but selecting a face is not a problem with version 0.6.7.0_5. I realize a lot has changed, but its better to mention something that doesn't matter than not mention something that does.
The older version can be installed version with:
pkg_add -r k3d
or
cd /usr/ports/graphics/k3d
make install
I can do the mug demo without a problem in this older version.
I also checked on the two patches that were being applied by the FreeBSD port, and one no longer appears to apply and the other is already a permanent change.
So, to clarify, the only error here is that K-3D wasn't warning you about this problematic Mesa version. I've committed a fix that should address this - if you grab the latest sources and rebuild, you'll get a warning message at startup. Obviously, that doesn't solve the problem for you, but the real fix would be to upgrade the FreeBSD libGL port to a later version of Mesa.
Cheers,
Tim
Ok, it looks like Mesa 7.6.1 is available on FreeBSD.
You just have do make WITHOUT_NOUVEAU in order for the new version to be pulled.
portsnap fetch update
cd /usr/ports/graphics/libGL/
make deinstall
make WITHOUT_NOUVEAU=yes installcd /usr/ports/graphics/libGLU/
make deinstall
make WITHOUT_NOUVEAU=yes installcd /usr/ports/graphics/libGLw/
make deinstall
make WITHOUT_NOUVEAU=yes installcd /usr/ports/graphics/libglut/
make deinstall
make WITHOUT_NOUVEAU=yes installcd /usr/ports/graphics/dri/
make deinstall
make WITHOUT_NOUVEAU=yes install
So I am getting these new OpenGL libraries updated and I should be able to test tomorrow.
However, now when I launch K-3D, I get this:
INFO: Loading plugin NGUI

[jared@FBSD8 ~/build-k3d]$[/CODE]
Of course, I updated gtkglext but same issue.
We know that Mesa 7.6.1 works fine with gtkglext on other platforms, so I'd suspect that there are other dependencies that need to be updated.
I see a couple of items you might try at http://forums.freebsd.org/showthread.php?p=67852

Timothy,
I have the Mesa libs updated. And glxinfo is working.
The selecting of the faces is now working properly. Yeah, one more issue surpassed.
So walking through the mug example here is what is still not working on FreeBSD:
1. The extrude interface appears to work until I try to change the Inset. The Inset setting doesn't do anything.
2. When I make the mug handle, the dissolve and bridge didn't work. I can't tell if a dissolve occurred but definitely no bridging occurs.
These are errors of omission, not specific to FreeBSD; I've added some tracker items to address them before the 0.8 release.
Thanks!
Tim
Following-up on this ...
* Group Faces is off by default for ExtrudeFaces.
* Inset functionality when Group Faces is on is restored.
* The BridgeFaces plugin is restored ... not sure what you were using ... BridgeEdges?
I hope to restore Dissolve in the next few days. Again, not sure what you would have been using in your testing, since the Dissolve plugin was completely disabled? Anyway, fixing Dissolve is one of two final items before the 0.8 release.
Cheers,
Tim
