again my isometric engine

After analizying my code, I feel that Im doing something wrong. So, i would like to ask if somebody has some similar implementation that can share with me so I can see the right method.
The problem is that I dont know if I must add all nodes to the scene or simply the nodes in the area Im going to render. If i have to add all nodes, how can I optimize rendering to avoid displaying non visible areas?

The engine does an 'automatic culling', so you could add all scene nodes if you like.Tthe bounding box of every scene node is tested against the view frustrum before rendering. This works very well for <1000 objects, but if you have more, you'll have to do it your own or wait for some new releases, or it would be too slow.

Add only the nodes that you need.

After playing Disgaea, I started playing around turning my BlockQuest code into a turn based isometric game and strangly, it's working well.

Though, the gameboard I use ends up only being 50x50 (maximum of 2500 tiles to stand on)

If your trying to have the world continue expanding, this page may give you some ideas on how to handle it.

Indeed, after fixing my code I noticed it runs faster now (before I was adding nodes right before render and several times, surely it was stupid).
