I want to add a TrackballDragger to a simple geometry (triangles,
normals calculated by SmoothingVisitor, colors, no other state set). My
viewer is configured with setLightingMode(osg::View::SKY_LIGHT). And my
graph looks really just like this:
root
/ \
/ \
/ MatrixTransform
/ \
Dragger \
Geometry
Dragging works perfectly but the lighting for the Geometry changes (goes
dark) and even setting GL_LIGHTING to ON | PROTECTED does not change
anything.
The change is introduced by TrackballDragger::setupDefaultGeometry but I
cannot see where the code should set a StateAttribute that would affect
lighting in my geometry.
Any hints how to debug this further or which StateAttributes need to be
enabled in my geometry?
Cheers,
Philipp Moeller
