Due to the updateVisitor behavior, seems that it's better using NodeCallbacks

Hi Torben,
I'm not the author of genwrapper, just the maintainer of the OSG side,
and as yet I haven't tried using genwrapper outside the OSG, but it
should be possible to get it to build wrappers for your own C++
classes.
As inspiration I would suggest having a look at how
Hi Steven,
I think that this issue might have been resolved in 2.8.2. I would
strongly recommend upgrading to 2.8.2. The API changes should be
pretty isolated w.r.t 2.2 so porting should be quite straight forward
and you'll get lots and lots of bug fixes as well as general
improvements. And..

Hi Wyatt,
I don't know where to start as I don't understand your point of
confusion. The best thing you can do is go look at the
include/osg/Unform header, and the examples that use uniforms, just do
a search through the OSG sources for osg::Uniform to see how it's
used.

This is impossible because all example uses generated library, includes and

I'm trying to simply project any 3D point ,which is already in world space,
into screen space.
I know how to do it without osg :

Those coordinates are in [0, 1] range, so multiply
Hi Harold,
OSG uses standard C arrays to store matrices. Which means these are row major
matrices. This changes order of operands. You should multiply point by matrix
not matrix by point. In your code you should rather preMultiply the matrices.
example:

Hi,
I suspected that as well ... but I browsed the source code for 2.8.2 and it
looked like it would exhibit the same problem.
It might be a couple months before I am able to upgrade to 2.8.2.
Thank you!

You don't create/set the whole struct at once, but the individual

I got good results doing it after the application has been fully

I would suggest first make installing OSG somewhere. Then create a small
