Hi Peter,
I'm trying to set up an Update Callback in osg::Geometry to
dynamically change the color of a vertex. I get no error, but my code
is not evaluated ( cout in Callback is not printing ). I attached my
Callback to osg::Geometry ( a simple Quad ) and setDataVariance(
osg::Object::DYNAMIC ) ;
If you look at the docs for osg::Drawable::UpdateCallback, its callable
method doesn't have the same signature as an osg::NodeCallback (which is
what you seem to have used)
http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00193.html
virtual void update (osg::NodeVisitor *, osg::Drawable *)
So it's normal that your operator()(...) isn't being called. :-)
Hope this helps,
J-S
