ok, I see your problem. The function is still there, but its name
changed to renderActionEnterHandler (in order to be symmetric with the
new renderActionLeaveHandler).
Allow me to give a bit of background on why this changed: At some point
in the early life of OpenSG Geometry was allowed to be not only used in
leaf nodes, but also in interior nodes of the graph. In other words
Geometry is implicitly a Group as well. For the frustum culling to work
correctly it has to push visibility information on a stack during
traversal and pop it when leaving the node. To make that work properly
the MaterialDrawable::renderActionLeaveHandler was added.
The question now is, what you are doing with the renderActionHandler and
if it is sufficient that your application only deals with the enter
callback ?
Thanks,
Carsten
