[osg-users] Dragger::setupDefaultGeometry changes lighting
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?

Hi Philip, Check your geometry to see if it has normal and colour arrays, it could be that these are missing so it's inheriting the values from the manipulator geometry. Robert.

Indeed my normals were missing. I had an updateCallback set on my Geometry that didn't apply SmoothingVisitor to the parents. Although the way I do it now looks highly inefficient to me. // g is the geometry the visitor is acting upon auto parents = g-getParents(); for(auto x : parents) if(Geode* geo = x-asGeode()) geo-apply(smoothingVisitor); Is there a subcomponent of SmoothingVisitor that can be applied to a Drawable instead of a Geode? I image it should be somewhere in the eternals already, but this seems useful to me. Philipp Robert.
