I think I just found some code that would do what I want. Let me know if there
is a better way of doing this both in regard of the custom active area and the
drag issue.
So I found this in osgManipulator but I belive I could use this code
independantly of it. The idea is to add a cull callback that does nothing and
returns true.
Code:
class ForceCullCallback : public osg::Drawable::CullCallback
{
public:
virtual bool cull(osg::NodeVisitor*, osg::Drawable*, osg::State*) const
{
return true;
}
};
void osgManipulator::setDrawableToAlwaysCull(osg::Drawable& drawable)
{
ForceCullCallback* cullCB = new ForceCullCallback;
drawable.setCullCallback (cullCB);
}
