Hi all -- I've just committed the final feature, the backport of the trunk 3DS
plugin. We're getting very close to a 2.8.5 final release!
I've now created 2.8.5 RC2:
http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.8.5-rc2
Thanks to all for your testing so far.
Thanks! This is in r12464 on the 2.8 branch.

Also, you mentioned some additional changes to osgconv. I'm still waiting on

The only other work to be done is the 3ds backport, and I understand that's in

Back to the original poster, then... Does this eliminate a need for a
transpose() function in the Matrix class?
I'm not 100% sure. My primary motivation for the transpose() function was to
compute a normal matrix (so it could be passed to glsl as an osg
, but produces incorrect results when compared to the
(correct) results of osg::Plane::transform().
I'm on 2.8.3, so perhaps there have been improvements on trunk?

- Add a transpose() function to Matrixf and Matrixd
Rather than a transpose() function, I wonder if anyone else would be interested
in seeing support for two different operator*() methods to handle vector/matrix
multiply, namely:
osg::Vec4 v;

Object linear TexGen isn't positional state so can be applied in the

Ah! Thanks, this was my problem. I mistakenly thought OpenGL transformed the
object planes by the modelview
like I'm doing everything
right, I'll post a small example that fails, or dig into the OSG code. More than
likely, I'm doing something wrong here, so I just wanted to ask what the
intended usage is.
Thanks,

this is a problem your app has already
solved.
osgBullet currently doesn't have any examples that show how to do this
save/restore, but contributions are welcome.

I'm reading this thread and laughing because I bought the eBook version direct
from the publisher, downloaded it, and was reading it in minutes. :-)

Thanks to osgBullet for the physics !
Cheers,
Nice, thanks for posting that. Well done.
What body tracking software are you using? Is it open source?

for FOV could be confusing. I usually modify FOV with ctrl right mouse in my code.

Very cool, thanks for posting that.
I've been planning on using a Kinect for this type of work, but haven't had time
to find a decent driver yet...

Hi all,
Just thought I would post this link to a homemade 3d scanner.
All you need is
at how the osgstaticviewer example brings in plugin symbols.
Then, if you are still unable to get it to work, post back with more specific
questions.
