[osg-users] Executing subtree multiple times / repeater node?

[Robert Osfield]

Hi Antiro,

If you just want to render whole subgraphs subgraph multiple times then a
cull callback can be used, or have a custom node override traverse() and
handle the CullVisitor as a special case and traverse the subgraph multiple
times.  When you use this approach you will typically alter the rendering
for each pass by pushing/popping StateSet or other controls onto the
CullVisitor to specialize the rendering state for each pass.

Robert.
