Hi John,
You can update the scene graph from your main frame loop, or assign an
custom UpdateOperation to the viewer.
// the expanding frame loop (equivilant to viewer.run())
while(!viewer.done())
{
viewer.advance();
// do you stuff here.
viewer.eventTraversal();
// or here...
viewer.updateTraversal();
viewer.renderingTraversals();
}
