Simple question from someone that hasn't follow the development in
detail for a long while
What is the simplest way of generating a terrain mesh from a 2D image
with heights? Im not looking for paging textures, terrain etc, just
image- mesh.
There use to be the osgDem app that did this, but
Hi users
I've noticed that the Qt examples set the threading model to SingleThreaded.
I tried changing the threading model (by using the ThreadingModelHandler)
but it crashes right after changing the threading model. I am guessing this
has something to do with the fact that one is only allowed to

After a while I finally took the time to replace my old 2.3.7
installation on IRIX with 2.4.0. Apparently the MIPSPro compiler
dislikes one little piece in the following changeset:

Hi all,
I'm currently developping VRJuggler/OSG apps, based on osgUtil::SceneView.
I'm considering using osgViewer::CompositeViewer instead.
Does someone have an experience of porting a VRJ/SceneView app to VRJ/osgViewer
? (I've seen an old thread in the list but no follow up).
I'm looking for
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.

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

Hi,
I have a question about computeLocalToWorldMatrix in camera class.
First, since the openscenegraph use row matrix instead column matrix like
opengl, I thought the default matrix multiply should be post multiply so that :
V' = M*V (opengl premultiply) chanage to
V' = VT*MT

I tried twice to send this replay with the CmakeCache.txt as an attachment and

Hi all,
I'm having some issues regarding OcclusionQueryNode. I draw an object as
a set of faces and a set of edges, and I can't seem to get OQN to deal
with both as a single entity, resulting in an artifact where for a fixed
camera position the object becomes intermittent (disappears, then
There's a Sourceforge project written by Heinrich Fink which adds some
support for ColladaFX to OSG's Collada plugin.
http://sourceforge.net/projects/collada-cg2glsl/
The code is in the osgdae_patch folder. I've never used the code and I
don't know if it'll need to be modified to get it working
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?
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

Trying to modify the osgscribe example. I want to display the scribe
lines, without the underlying model beneath it.
The code does the following:

The decorator setups up the scribe mode. If I then set the nodeMask

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

Hmmm, must have been the attachment since you saw everything on this one.
Attachment was only 47kb - you wouldn't think that would be a stopper unless it was

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.

Maybe you can try sending the attachment from different mail account?
