I think you need to use PositionAttitudeTransform (OSGQSG.pdf page 49) but
there's a big chance that I misunderstand the case.

Hi Guy,
Thanks for your response. I think we are thinking of different
manipulators. I'm talking about the classes in the osgManipulator
namespace. Were you referring to camera manipulators like the trackball?

Hello Julian,
What EXACTLY are you trying to achieve?
Do you need some objects (GUI objects if I understand correctly) to have
their own transformations without being affected by the Manipulator?
If so, you can use set the transformation to ABSOLUTE_RF.

If you mean you just want to display your model in wireframe, you could use
the PolygonMode StateAttribute for that.

Trying to modify the osgscribe example. I want to display the scribe
lines, without the underlying model beneath it.
The code does the following:
root->addChild(decorator);
decorator->addChild(loadedModel);
The decorator setups up the "scribe mode". If I then set the nodeMask

OSG doesn't assume left- or right-handed coordinates. It is based on OpenGL,
in which object coordinate space is left-handed, but can easily be switched
to right-handed with a negative scale.
In my experience, most transformation confusion stems from not knowing
whether to pre- or post-multiply ma
hi,
i am working with osg 2.4, osgCal 0.3.0 and cal 3d 0.11.
in the cal3d faq i read:
"It should also be noted that Cal3D's math classes assume a left-handed
rotation system."
i have trouble with setting the quaternions from osg to the cal3d model.
which coordinate system do osg::Quat use?
There's a Sourceforge project written by Heinrich Fink which adds some

We are building OSG for the x64 configuration using Visual Studio 2005 SP1.
OSG compiles successfully but it appears that I will need to do some more
work on the plug-ins in the 3rd Party dependencies. Has anyone posted
step-by-step instructions for that or has anyone posted any precompiled

Anders,
I believe osgdem is part of VPB now. When you build VPB, it compiles to
osgdem that can be run from the command line just as in the past.
