Hello,
I use osg:: LineSegment to perform an intersection between a ray starting from
a wand and the objects in my scene. Here is my code:
osg::Vec3 wandpt1;
osg::Vec3 wandpt2;
line = new osg::LineSegment(wandpt1,wandpt2);
osg::BoundingBox modelbox;
modelbox.expandBy(modelTransf->getBound());
Hello
Yes, great job !
There was an other problem : I did an optimize() of my model ; at that moment,
all stateSet lost their geode parent... and all of them were suddenly linked to
the same and main parent (the cabine of the aircraft).
Now is much better !
Thanks again.

Hi Lucie,
take a look to osgPick example to see the correct way of using intersection
visitors and routines.

Hi Emmanuel,
If you are trying to create a stack of images as a single volume then
use the --images command line option.

Hi Manu,
You data DICOM data rendering suggests that the air around the subject
is returning a high intensity value rather than a low one. This is
not something I've seen with the DICOM datasets I've tested, so try
other data. A transfer function would certainly be one way to pick
out the data y
Hi,
Hehe, now that you have succeeded at getting something, you start to get into
the problematics of volume rendering. Namely, to get a nice visual
representation, you have to provide a suitable transfer function. The example
uses some hard-coded transfer function (osgVolume supports only 1D T
HI all,
I have tried to change my email address for the submissions list, it never
sends me an email for my password to change it.
Can anyone help?
I have managed to change osg-users, if this comes through!

Hi,
I'm thinking about using OSG functions in my engine, but some things about OSG
aren't obvious for me, so, i want to ask advanced users for exact info:
1) Is it hard to change components of OSG, to meet my requirments and use my
own version within scene graph integrated? For example, i'm not
Hi all,
just a short heads-up. As suggested by Mathieu Marache I am using now
the semi-official osg-git-repository and a custom branch called iphone
for further development.
You'll find it here:

I'll abandon the old github project at

Hello,
I'd like to get OSG support collada files out of the box in debian.
I created a debian package for collada-dom, and I'm currently waiting

Hi Robert,
I think the solution of having a GUIEventHandler through Viewer to capture and
pass along all events will be the way I go.
I was trying to have various users on our end write their own event handlers

I'm trying to get a stereo setup to work with osg.

Hi Tom,
Another solution would be to subclass from osgViewer::Viewer and add
your own removeEventHandler method, then once you move to 3.0 you'll
just be able to drop your own Viewer class or just remove the method,
and optional compile would even let you build against 2.9.x/3.0 and
2.8.x without

The easiest way to do what you want is place your six RTT Camera's as
nodes in the scene graph and have a callback in on them that switches
them off either via a NodeMask or via an osg::Switch node so that they
only render for one frame, or one nominated frame, or whatever metric
