Hi Martin,
Some of this I can do with stateattribute so that eg. a gridline is always
drawn with no lighting but for things like picking the intersector visitor must
explicitly know to ignore a grid.
The point was to make a distinction between real model elements and
'decoration' elements - I just wondered if there was a common practice way of
doing this.
Why not just devote a bit in the nodemask for such elements? Then you
set the intersection visitor's traversal mask to ignore those elements.
const unsigned int NODEMASK_UNPICKABLE = 0x1000; // whatever
iv->setTraversalMask(~NODEMASK_UNPICKABLE);
That's how we do it.
