Hi John,
osgText::Text doesn't need an update traversal to sync itself after an
update, so it should be possible to update the text, draw the text,
update the text etc. As to why this doesn't work in your case I do
not know, its hardly a part of design spec for osgText.
I would however suggest
HI Nick,
Try getting the camera manipulator to recompute its home position when
you change the scene via:
viewer.getCameraManipulator()-computeHomePosition();
Or just set it manuual via:
viewer.getCameraManipulator()-setHomePosition(...);

Sorry forgot to mention, these calls just set the home position, they
don't actually move the camera to the home position. To move the

If I have view frustum culling enabled, and I put the text on the screen
using native glOrtho() calls, but the text's transform only contains a
screen coordinate, would it get wiped out because of that? Should I be
using osg's transforms to make the HUD text? I think maybe it is being

You should read Design Patterns and familiarize yourself with the callback
pattern.
OSG calls operator()() as part of the callback process. You insert code into
that method to do whatever you need to do in your callback.

Take a look at glBlendColor in the blue book. In OSG, the BlendColor

Hi Mike,
Take a look at OpenGL's two-sided lighting support via
glLightModel/GL_LIGHT_MODEL_TWO_SIDE (and exposed in OSG with
osg::LightModel). I think that's the more elegant solution your looking
for.
Mike Wittman

Sounds like you want something like:
osg::ref_ptrosg::LightModel lightModel = new osg::LightModel;
lightModel-setTwoSided(true);
myTwoSidedGeode-getOrCreateStateSet()-setAttribuiteAndModes(lightModel.get

Might not be the exact syntax but pretty close.

In case it's not obvious, with two-sided lighting you do not need to
