I'll look at osgViewer::Viewer, the reason I used osgViewer::CompositeViewer
is because the methods it provided made implementing something very easy.

Hi Phishjam,
Is it simply that you want the viewers camera to follow a child in the
scene? If so then you can use either node-getWorldMatrices() to get
the list of model matrices of the a node in the scene, inverting this
then gives
you the view matrix. Note, getWorldMatrices() may return 1 or

You always have to call cull() before draw(), even
osgViewer::Viewer::renderingTraversals()
does this internally. cull() is what culls the scene graph

This morning I awoke and had an idea about why the compile bit be

The CoordinateFrame relates the standard OpenGL coordinate frames - the options:
enum CoordinateFrame

Which mean

Hi Michael,
Thanks for reporting this. When I updated the link for 2.4 binaries
openscenegraph.dachary.org was working, with Loic having just repaired
it from being hacked. So depressing to see it hacked again within
days ;-|
Thanks to Jose for fixing this so quickly.

hi everyone，
I am puzzled by the method of drawing text.
Three is three main sentences in the function
Text::drawForegroundText(...)
{
state.setVertexPointer( 3, GL_FLOAT, 0, (transformedCoords.front()));
state.setTexCoordPointer( 0, 2, GL_FLOAT, 0,
Hi Robert,
The solution is either to add a block that prevents the first frame
from commencing till all the CompileOperations have been complete, or
to move the compile into the osgViewer::Renderer::draw()
implementation, so the compile is done after cull, but before the
first draw(). The

ea-setTime( _gw-getEventQueue()-getTime() );

Hi Joakim!
I know what's wrong here. The geode, which has the cull callback, has an
absolute reference frame. That's why you don't get the expected values
from the cullvisitor.

Would it be worth while to link to the official Debian repository there?

Between the stable, testing, and unstable branches, there are packages
for OSG 1.2, 2.2, and 2.4 on multiple platforms.
These may always be the most up-to-date,

I did some testing. Fix seems to work at my Home. No red frames at all.
However there seems to be an issue
with --CullThreadPerCameraDrawThreadPerContext mode which looks like a
deadlock after third frame (plane moved three times and stopped). Mode can
