Hello all, is there a way in which I can change the default scales in OSG?
What I mean is that it orients itself in a particular way (x,y,z); is there a
way that I can change the default without having to do it manually?

I am looking to figure out how to give thickness to line segments. I am
creating them as follows
Code:
osg::ref_ptrosg::Geometry geom = new osg::Geometry;
osg::ref_ptrosg::DrawArrays drawArrayLines = new
osg::DrawArrays(osg::PrimitiveSet::LINE_STRIP);
ok, ive been playing around a little bit here and i seem to have hit a wall. i
was wondering how OSG goes about representing unique trajectories (conceptually
i would guess a collection of line segments). here is what i am doing now (mix
of pseudocode and c++):
Code:
//appropriate variables
I've gotten a little farther. Got around to checking out OpenSceneGraph 3.0
Beginner's Guide and if anyone else comes along on this forum in my position,
do yourself a favor and purchase this book.
Anyway, one question that I am having is this:

Hello all, its me again.
I was reading more into that e-book tutorial listed earlier in this thread. I
copy-pasted the example on how to build a simple scene graph (p53), which
consists of just a single quadrilateral.
It compiles fine but blows up when it tries to link. I have made sure that
That was it. Thanks again.

Ok, I am trying to write a node to file (pretty much just verbatim stuff from
the e-book). When I make this call:
bool result = osgDB::writeNodeFile(*(root.get()), fileName );
result comes back as false and a warning message is output saying that it

The filename is a .osg file.
I couldn't make heads or tails of that link you provided; is it telling me to
set an environment variable or send it a compiler option?

Okay, I'm back again.
I just wrote a quick parser for my cluster files, read some more from an OSG
tutorial and then went to poke around in the code.
The dilemma now is this: when I include any OSG headers, I get tons of
compiler errors eminating from the base OpenGL files (i.e. residing at

at least). I uploaded it to my website, you can check it here:

Ok, I deleted the build folder and restarted with the method you listed above
and I am still getting massive amounts of errors (including the cannot find

Here is what I am doing:

(i.e. D:\OpenSceneGraph)

Should it matter which version of OSG I am working with? In other words, should
I upgrade to 2.9.16?
And by awkward, do you mean nobody knows why this is failing for me?

GNUplot doesn't really fit the domain here. Last time I played around in it, it
only dealt with planes in 3d.

Well I am working on a utility for an airport simulation. Parts of the program
were already written in OSG by another developer but he is pat-time and
off-site so any help from him is pretty much not going to happen. My boss
wanted something plotted in OpenGL (originally he mentioned glaux but

ALL_BUILD with the same results (massive errors). Any ideas?

I am aware. However, when I do a build solution on ALL_BUILD, it still produces
the same slew of errors.
