Hi Art,
Of course the amount of repeats should be changeable during run time, hence simple multiple "copy" of group A will not work.
Make a subclass of osg::Group which has an overridden traverse() method,
which is like this:
void traverse(osg::NodeVisitor& nv)
{
for (unsigned int i = 0; i < _numRepeat; ++i)
{
osg::Group::traverse(nv);
}
}
and with a getter and setter for the _numRepeat variable... Maybe add a
copy-ctor that takes an osg::Group to replicate any group, and a static
function that allows it to replace a group in-place easily...
You could also customize the traverse so that the children are traversed
only once for update traversals, but _numRepeat times for cull
traversals, if all you want is X number of renders.
Does that work for you?
J-S
