Hi all,
Quick question. Say I want to make a headlight (like the light source
that's added to the viewer by default if no lights are in the model),
where should I add it in my graph?
Say I have a single view with a single camera, I tried adding an
osg::Light to the camera's stateset. That doesn't work, the light seems
to be in a fixed position at all times, even if I move the camera around.
Do I need a callback to explicitly change my light to match the view
direction each frame? I don't think the viewer needs that, I think it
happens automatically, because I can't find any code related to that...
Then again, the only code I can find related to the headlight is in
SceneView.cpp, where it says:
if (_light.valid())
renderStage->addPositionedAttribute(NULL,_light.get());
Not sure how I can do something equivalent from outside viewer code...
Can anyone offer some guidance please? Thanks in advance,
J-S
