You don't normally draw "on demand" with a scene graph, it's purpose is to manage the culling and draw dispatch for you. There are times when you can manage low level rendering, but this tends to be niche task done for very specific techniques, it's something I'd expect advanced users might consider occasionally, but for the most part users will likely never call the low level draw code themselves. Could you take a step back and explain what you are trying to do at a higher level. I suggest this as there may well be a much more straight forward way of doing things that starting to get your hand dirty with low level stuff.
